'''Physical attractiveness''' is the extent to which a person's physical features are considered [[aesthetics|aesthetically]] pleasing or [[beauty|beautiful]]. The term often implies [[sexual attraction|sexual attractiveness]] or desirability but can also be distinct from them. Many factors influence one person's attraction to another, with physical aspects being one of them.

==General contributing factors <span class="anchor" id="Determinants of female physical attractiveness"></span>==
Generally, physical attractiveness can be viewed from a number of perspectives; with universal perceptions being common to all human [[culture]]s, cultural and [[society|social]] aspects, and individual subjective preferences. The perception of attractiveness can have a significant effect on how people are judged in terms of employment or social opportunities, [[friendship]], sexual behaviour, and [[marriage]].<ref name="Lorenz-2005">{{cite web | last = Lorenz | first = Kate | name-list-style = vanc | date = 2005 | url = http://www.cnn.com/2005/US/Careers/07/08/looks/ | title = Do Pretty People Earn More? | work = www.CNN.com }}</ref>

A 1921 study of the reports of college students regarding those traits argued that static traits, such as beauty or ugliness of features, hold a position subordinate to groups of physical elements like expressive behaviour, affectionate disposition, grace of manner, aristocratic bearing, social accomplishments and personal habits.<ref>{{cite journal| vauthors = Perrin FA | title = Physical Attractiveness and Repulsiveness | url = https://archive.org/details/sim_journal-of-experimental-psychology_1921-06_4_3/page/203 | journal = Journal of Experimental Psychology | volume = 4 | issue = 3 |date=June 1921 | pages = 203–17 | doi = 10.1037/h0071949}}{{dead link|date=March 2024}}</ref>

===Facial features===
An Italian study published in 2008 analyzed the positions of the 50 [[soft-tissue]] landmarks of the faces of 324 [[white people|white]] [[Northern Italy|Northern Italian]] [[adolescent]] boys and girls to compare the features of a group of 93 "beautiful" individuals selected by a commercial [[casting (performing arts)|casting]] agency with those of a reference group with normal dentofacial dimensions and proportions. The research found that, in comparison with the reference group, the attractive adolescents tended to have the following characteristics:
* the ratio between the volume of the [[forehead]] and that of the total face was larger;
* the [[nose|nasal]] volume was smaller;
* the distance between outer [[canthi]] was larger;
* total facial height and depth were reduced.
Some tendencies differed by age and sex:
* the facial volume was smaller in older attractive boys than in their peers, but bigger in attractive girls;
* the faces of older attractive adolescent boys were less rounded (bigger ratio between facial area and [[volume]]), but the reverse was true for girls of any age;
* attractive older boys had smaller angles of facial convexity with more acute profiles, while in girls the reverse pattern was found;
* the nasolabial angle was reduced in girls, but in older boys the effect was reversed;
* older attractive boys tended to have more prominent [[chins]].
The study concluded that attractive adolescents had more [[neoteny|neotenous]] and juvenile features, but older attractive boys also showed tendencies towards [[sexual dimorphism]].<ref>{{cite journal |last1=Sforza |first1=Chiarella |last2=Laino |first2=Alberto |last3=D'Alessio |first3=Raoul |last4=Grandi |first4=Gaia |last5=Tartaglia |first5=Gianluca Martino |last6=Ferrario |first6=Virgilio Ferruccio |title=Soft-Tissue Facial Characteristics of Attractive and Normal Adolescent Boys and Girls |journal=The Angle Orthodontist |date=September 2008 |volume=78 |issue=5 |pages=799–807 |doi=10.2319/091207-431.1 |pmid=18298221 |doi-access=free }}</ref>

===Symmetry===

Symmetrical faces and bodies may be signs of good inheritance to women of child-bearing age seeking to create healthy offspring.

===Genetics===

Studies have explored the genetic basis behind such issues as facial symmetry and body scent and how they influence physical attraction.

===Youthfulness===

A 2010 study by American dating site [[OkCupid]] on 200,000 of its male and female users found that heterosexual women—except those during their early to mid-twenties—are open to relationships with both somewhat older and somewhat younger men; they have a larger potential dating pool than men until age 26. At age 20, women, in a "dramatic change", begin sending private messages to significantly older men. At age 29, they become "even more open to older men". Male desirability to women peaks in the late 20s and does not fall below the average for all men until 36.<ref name="Rudder-2010" /> Other research indicates that women, irrespective of their own age, tend to be more attracted to men who are the same age or older.<ref>{{cite journal|last1=Antfolk|first1=Jan|last2=Salo|first2=Benny|last3=Alanko|first3=Katarina|last4=Bergen|first4=Emilia|last5=Corander|first5=Jukka|last6=Sandnabba|first6=N Kenneth|last7=Santtila|first7=Pekka|date=2015|title=Women's and men's sexual preferences and activities with respect to the partner's age: evidence for female choice|journal=Evolution & Human Behavior|volume=36|issue=1|pages=73–79|doi=10.1016/j.evolhumbehav.2014.09.003|bibcode=2015EHumB..36...73A |name-list-style=vanc}}</ref>

Today, men and women's attitudes towards male beauty have changed. For example, body hair on men may even be preferred ([[#Body hair|see below]]).

A 1984 study said that gay men tend to prefer gay men of the same age as ideal partners, but there was a [[Statistical significance|statistically significant]] effect ([[p-value|p]] < 0.05) of masculinity-femininity.

25% of [[online dating]] website [[eHarmony]]'s male customers over the age of 50 request to only be matched with women younger than 40.{{r|Reitman-2004}} The 2010 OkCupid study found that female desirability to its male users peaks at age 21, and falls below the average for all women at 31. After age 26, men have a larger potential dating pool than women on the site; and by age 48, their pool is almost twice as large. The median 31-year-old male user searches for women aged 22-to-35, while the median 42-year-old male searches for women 27-to-45.

Signals of fertility in women are often also seen as signals of youth. The evolutionary perspective proposes the idea that when it comes to sexual reproduction, the minimal parental investment required by men gives them the ability and desire to simply reproduce 'as much as possible.'<ref name="rozenberg-2016">{{cite web|title=Attraction and Relationships – The Journey from Initial Attachments to Romantic Love: Rozenberg Quarterly|url=http://rozenbergquarterly.com/attraction-and-relationships-the-journey-from-initial-attachments-to-romantic-love/|access-date=March 3, 2016|website=rozenbergquarterly.com}}</ref> It therefore makes sense that men are attracted to the features in women which signal youthfulness, and thus fertility.<ref name="rozenberg-2016" /> Their chances of reproductive success are much higher than they would be should they pair with someone older—and therefore less fertile.

This may explain why combating age declines in attractiveness occurs from a younger age in women than in men. For example, the [[Hair removal|removal of one's body hair]] is considered a very feminine thing to do.<ref name="Barber-1995">{{cite journal|vauthors=Barber N|year=1995|title=The evolutionary psychology of physical attractiveness: Sexual selection and human morphology|journal=Ethology and Sociobiology|volume=16|issue=5|pages=395–424|doi=10.1016/0162-3095(95)00068-2}}</ref> This can be explained by the fact that aging results in raised levels of [[testosterone]] and thus, body hair growth. Shaving reverts one's appearance to a more youthful stage<ref name="Barber-1995" /> and although this may not be an honest signal, men will interpret this as a reflection of increased fertile value.

Average-looking hands give an indication of an individual's health (because there are no abnormalities).

The healthier-looking the skin on the hands, the more attractive they appear. Reasons given for this say skin health may reflect an individual's overall health. Healthy skin can show that someone is free from illness because some illnesses have a bad effect on the look of skin. These features are found attractive because they show that the person has good [[gene]]s and is therefore a suitable mate to reproduce with. Skin health may also give an indication of socioeconomic status, as rough hands may indicate a low-paying, laborious job. Low socioeconomic status might show that someone does not have resources to provide for the offspring, and is therefore less attractive. The more fat the hands appear, the less attractive they are. This is because of the [[Comorbidity|co-morbidity]] associated with obesity. If someone is overweight, they may have another disease, which means they may not be able to produce healthy offspring. The attractiveness of the hands also gives an indication of other features of the individual; people with more attractive hands have been found to be taller and slimmer.<ref name="Kościński-2011" /> In most of these hand attractiveness studies, only white, European hands were used, and the participants were 18–26 years old. So, the attractiveness of non-white hands and of different age groups was not tested. Also, the people who rated the hand attractiveness were white Europeans, so their ratings may not represent how individuals of other skin colours and cultures would rate the hands.

Other studies have shown that heterosexual women often prefer men taller than they are, rather than a man with above average height. While women usually desire men to be at least the same height as themselves or taller, several other factors also determine male attractiveness, and the "taller male" norm is not universal.{{sfnp|Sear|Marlowe|2009}} For example, taller women are more likely to relax the "taller male" norm than shorter women.<ref>{{cite journal|vauthors=Courtiol A, Raymond M, Godelle B, Ferdy JB|date=August 2010|title=Mate choice and human stature: homogamy as a unified framework for understanding mating preferences|journal=Evolution; International Journal of Organic Evolution|volume=64|issue=8|pages=2189–203|doi=10.1111/j.1558-5646.2010.00985.x|pmid=20199563|doi-access=free }}</ref> Furthermore, professor Adam Eyre-Walker, from the [[University of Sussex]], has stated that there is, as yet, no evidence that these preferences are evolutionary preferences, as opposed to merely cultural preferences.<ref name="BBC News-2002">{{cite news |date= August 14, 2002 |url=https://news.bbc.co.uk/1/hi/health/2190461.stm |title=Tall men 'top husband stakes' |work=BBC News |access-date= October 15, 2009}}</ref> Still, the cultural perceived attractiveness preferences for taller men are powerful and confirmed by multiple studies.

====Standing postures====
[[File:VenusdArles2.JPG|thumb|A statue of Venus standing in a [[contrapposto]] pose with her weight borne predominantly on one leg. As shown here, this posture accentuates the curvature of her figure.]]
Standing in a [[contrapposto]] posture (with bodyweight predominantly supported by one leg which is either straight, or very slightly bent, and with the other leg slightly bent) has been found to be more attractive looking than standing in a more plain, upright posture. This was found to be the case for both men and women. This posture may lower a person's observable waist-hip ratio and make their hips look wider and their waists thinner. For women especially, this can accentuate the curvature of their figure on one side of their body and make them seem more attractive.

A study found that the same genetic factors cause facial masculinity in both males and females<!-- This statement was in the first sentence of the second paragraph of the "Discussion" section. --> such that a male with a more masculine face would likely have a sister with a more masculine face due to the siblings having shared genes.

Women focus primarily on the ratio waist to chest or more specifically waist to shoulder. This is analogous to the waist to hip ratio (WHR) that men prefer. Some studies have shown that attractive bodily traits in the eyes of a heterosexual woman would include a tall, athletic physique, with wide shoulders, and a slim waist area.<ref>{{cite book |last1=Buss |first1=David |title=Evolutionary Psychology: The New Science of the Mind |date=2 October 2015 |publisher=Psychology Press |isbn=978-1-317-34573-2 |page=[https://books.google.com/books?id=us1WCgAAQBAJ&pg=PT168 168]}}</ref> Research has additionally shown that college males had a better satisfaction with their body than college females.<ref name="Catikkas-2011" /> The research also found that when a college female's waist to hip ratio went up, their body image satisfaction decreased.<ref name="Catikkas-2011">{{cite journal | vauthors = Catikkas F | title = Physical correlates of college students' body image satisfaction levels. | year = 2011 | journal = Social Behavior and Personality | volume = 39 | issue = 4 | pages = 497–502 | doi = 10.2224/sbp.2011.39.4.497 | doi-access = free }}</ref>

Some research has shown that body weight may have a stronger effect than WHR when it comes to perceiving attractiveness of the opposite sex. It was found that waist to hip ratio played a smaller role in body preference than body weight in regards to both sexes.<ref>{{cite journal |last1=Furnham |first1=Adrian |last2=Tan |first2=Tina |last3=McManus |first3=Chris |title=Waist-to-hip ratio and preferences for body shape: A replication and extension |journal=Personality and Individual Differences |date=April 1997 |volume=22 |issue=4 |pages=539–549 |doi=10.1016/S0191-8869(96)00241-3 }}</ref>

Psychologists Viren Swami and Martin J. Tovee compared female preference for male attractiveness cross culturally, between Britain and Malaysia. They found that females placed more importance on WCR (and therefore [[body shape]]) in urban areas of Britain and Malaysia, while females in rural areas placed more importance on BMI (therefore weight and body size). Both WCR and BMI are indicative of male status and ability to provide for offspring, as noted by evolutionary theory.<ref>{{cite journal | vauthors = Swami V, Tovee MJ |title=Male physical attractiveness in Britain and Malaysia: A cross-cultural study |journal=Body Image |date=December 2005 |volume=2 |issue=4 |pages=383–93 |doi=10.1016/j.bodyim.2005.08.001 |pmid=18089203 }}</ref>

Females have been found to desire males that are normal weight and have the average WHR for a male. Females view these males as attractive and healthy. Males who had the average WHR but were overweight or underweight are not perceived as attractive to females. This suggests that WHR is not a major factor in male attractiveness, but a combination of body weight and a typical male WHR seem to be the most attractive. Research has shown that men who have a higher waist to hip ratio and a higher salary are perceived as more attractive to women.<ref>{{cite journal | vauthors = Singh D | title = Female judgment of male attractiveness and desirability for relationships: Role of waist-to-hip ratio and financial status. | url = https://archive.org/details/sim_journal-of-personality-and-social-psychology_1995-12_69_6/page/1089 | year = 1995 | journal = Journal of Personality and Social Psychology | volume = 69 | issue = 6 | pages = 1089–1101 | doi = 10.1037/0022-3514.69.6.1089 | pmid = 8531056 }}</ref>

Men's bodies portrayed in magazines marketed to men are more muscular than the men's bodies portrayed in magazines marketed to women.

In a cross-cultural study, Marcinkowska et al. said that 18-to-45-year-old heterosexual men in all 28 countries surveyed preferred photographs of 18-to-24-year-old white women whose faces were feminised using facial image editing software over faces of 18-to-24-year-old white women that were masculinised using that software, but there were differences in preferences for femininity across countries.

Michael R. Cunningham of the Department of Psychology at the [[University of Louisville]] found, using a panel of [[Asian American|East Asian]], [[Hispanic and Latino Americans|Hispanic]] and [[White American|White]] judges, that the female faces tended to be judged as more attractive if they had a mixture of youthful and sexually mature features.{{sfnp|Cunningham|Roberts|Barbee|Druen|1995|p=267|ps=: "Asian, Hispanic, and White participants were similar in giving higher ratings to targets with the neonate features of large eyes, greater distance between the eyes, and a smaller nose area (see Table 2). Women with the maturity qualities of higher cheek-bones and narrower faces and low levels of the male maturity cues of large chins and thick eyebrows were judged more positively."}} Using a panel of [[African Americans]] and Whites as judges, Cunningham found more neotenous faces were perceived as having both higher "femininity" and "sociability".{{sfnp|Cunningham|Roberts|Barbee|Druen|1995}} The authors found no evidence of ethnocentric bias in the Asian or White samples, as Asians and Whites did not differ significantly in preference for neonate cues, and positive ratings of White women did not increase with exposure to [[Western media]].{{sfnp|Cunningham|Roberts|Barbee|Druen|1995|p=271|ps= "The four-item measure of exposure to Western culture was not reliably associated with giving higher ratings to Whites (r = . 19, n s). The relation of rating Whites to frequency of viewing Western television, for example, was quite low(r=.01)."}}

Rather than finding evidence for purely "neonate" faces being most appealing, Cunningham found faces with "sexually-mature" features at the "periphery" of the face combined with "neonate" features in the "centre of the face" most appealing in women.{{sfnp|Cunningham|Roberts|Barbee|Druen|1995}} Upon analyzing the results of his study, Cunningham concluded that preference for "neonate features may display the least cross-cultural variability" in terms of "attractiveness ratings"{{sfnp|Cunningham|Roberts|Barbee|Druen|1995}} and, in another study, Cunningham concluded that there exists a large agreement on the characteristics of an attractive face.<ref>{{cite journal | vauthors = Cunningham MR |title=Measuring the Physical in Physical Attractiveness: Quasi-Experiments on the Sociobiology of Female Facial Beauty | url = https://archive.org/details/sim_journal-of-personality-and-social-psychology_1986-05_50_5/page/925 |journal=Journal of Personality and Social Psychology |volume=50 |issue=5 |pages=925–35 |date=May 1986 |doi=10.1037/0022-3514.50.5.925 |quote= Research with Western subjects disclosed significant consistency in evaluating attractiveness (Hatfield & Sprecher, 1986; Iliife, 1960).

BMI has been criticised for conflating fat and muscle, and more recent studies have concentrated on body composition. Among Australian university students, the most attractive body composition for women (10.31&nbsp;kg fat, 42.45&nbsp;kg muscle) was found to be lower in fat than both the most healthy appearing composition, and below the healthy range.<ref name="Brierley-2016" />

In the United States, women overestimate men's preferences for thinness in a mate. In one study, American women were asked to choose what their ideal build was and what they thought the build most attractive to men was. Women chose slimmer than average figures for both choices. When American men were independently asked to choose the female build most attractive to them, the men chose figures of average build. This indicates that women may be misled as to how thin men prefer women to be.{{sfnp|Buss|2003|pp=55,56}} Some researchers believe women themselves may play a role in enforcing the thinness ideal, however they assert that this does not mean that the ideal does not ultimately trace its origins to patriarchical norms (the "[[male gaze]]").<ref>{{cite book | last1=Germov | first1=John | last2=Williams | first2=Lauren | title=Weighty Issues: Fatness and Thinness As Social Problems | publisher=Transaction Publishers | series=Social Problems and Social Issues | date=1999| isbn=978-1-4128-4126-9 | page=[https://books.google.com/books?id=IHn-D7Q8KwMC&pg=PA125 125-127] }}</ref> Popenoe writes that societies with abundant food sources often value thin women, while those with food scarcity value women with fat bodies.

In Chinese, the phrase "willow waist" ({{lang-zh|c=[[wikt:柳|柳]] [[wikt:腰|腰]]}})<!--The source wrote the original Chinese phrase in Pinyin as "liuyao" rather than in the Chinese characters that are written here.--> is used to denote a beautiful woman by describing her waist as being slender like a willow branch.<!--This is in the fourth line of the first paragraph of page 15.-->{{sfnp|Kyo|2012|p=15}}

In the [[Victorian era]], a small waist was considered the main trait of a beautiful woman.<!--This is in the tenth line of the second paragraph on page 38.--><ref name="Silver-2004">{{cite book | vauthors = Silver AK | year = 2004 | title = Victorian Literature and the Anorexic Body | location = UK | publisher = Cambridge University Press | pages = 38, 48 | isbn = 978-0-511-03051-2 }}</ref> The term "[[wasp waist]]" describes an extreme fashion silhouette, produced by a style of corset and girdle.

===Feet size===
According to some studies, most men prefer women with small feet,<ref>{{cite journal | vauthors = Barber N |title=The evolutionary psychology of physical attractiveness: Sexual selection and human morphology |journal=Ethology and Sociobiology |volume=16 |issue=5 |pages=395–424 |date=September 1995 |doi=10.1016/0162-3095(95)00068-2 }}</ref><ref>{{cite journal | vauthors = Voracek M, Fisher ML, Rupp B, Lucas D, Fessler DM | title = Sex differences in relative foot length and perceived attractiveness of female feet: relationships among anthropometry, physique, and preference ratings | journal = Perceptual and Motor Skills | volume = 104 | issue = 3 Pt 2 | pages = 1123–38 | date = June 2007 | pmid = 17879647 | doi = 10.2466/pms.104.3c.1123-1138 }}</ref> such as in ancient China where [[foot binding]] was practiced.<ref>{{cite journal | vauthors = Berman JE | year = 1993 | title = Female Genital Mutilation, Yes, but Don't Condone It. | url = https://www.nytimes.com/1993/11/30/opinion/l-understand-female-genital-mutilation-yes-but-don-t-condone-it-015393.html | journal = The New York Times }}</ref>

In Jewish [[Rabbinic literature]], the rabbis considered small feet to be the ideal type of feet for women.<!--This is in the third line of the paragraph that starts with "Woman's legs..." at the top of page 214.--><ref name="Brayer-1986" />

===Hair===
Men have been found to prefer [[long hair|long-haired]] women.{{sfnp|Buss|2003|pp=51–54}}{{sfnp|Buss|2005|page=[https://books.google.com/books?id=esDW3xTKoLIC&pg=PA309 309]}} <ref>{{cite journal | vauthors = Bereczkei T, Meskó N | title = Hair length, facial attractiveness, personality attribution; A multiple fitness model of hairdressing | journal = Review of Psychology | volume = 13 | issue = 1 | pages = 35–42 }}</ref> An [[evolutionary psychology]] explanation for this is that malnutrition and deficiencies in minerals and vitamins causes loss of hair or hair changes. Hair therefore indicates health and nutrition during the last 2–3 years. Lustrous hair is also often a cross-cultural preference.{{sfnp|Sugiyama|2015}}

A component of the female beauty ideal in [[Persian literature]] is for women to have black hair,<!--This is in the paragraph that starts with "Daneshvar views..." on page 187. Having "black hair" is a rewording of the quote from the book which was "black-haired".-->{{sfnp|Milani|1992|p=215}} which was also preferred in Arabian society in the Middle Ages.<!--This is in the fourth line in the bottom paragraph of page 215.-->{{sfnp|Lane|1883 |pages = [https://archive.org/details/cu31924028628141/page/n233 214{{ndash}}216] }} In Middle English literature, curly hair is a necessary<!--The word "necessary" is a rewording of the source's phrase "absolutely essential".--> component of a beautiful woman.<!--This is in the first line of the last paragraph that starts with "That hair should curl..." on page 31.-->{{sfnp|Curry|1916|p=31}}

===Fertility-driven attractiveness===
There are some subtle changes in women's perceived attractiveness across the [[menstrual cycle]]. During their most [[Fertility|fertile phase]], there are observable changes in women's behaviour and physiology. A study conducted by G. Miller (2007) examined the amount of tip earnings by lap dancers across the menstrual cycle. He found that dancers received nearly US$15 more when they were near [[ovulation]] than during the rest of the month. This suggests that women either are more attractive during ovulation phase, or they experience a significant change in their behaviour.{{sfnp|Miller|Tybur|Jordan|2007}} Some other studies have found that there are subtle differences in women's faces when in their [[Fertility|fertile]] phase. Bobst and Lobmaier (2012) created 20 prototyped photographs, some of a female during ovulation and some during the [[luteal phase]]. Men were asked to choose the more attractive, the more caring and the more flirtatious faces. They found a significant preference for the [[follicular phase]] (ovulation). This suggests that subtle shape differences in faces occurring during the female's [[ovulation]] phase are sufficient to attract men more.<ref>{{cite journal | vauthors = Bobst C, Lobmaier JS | title = Men's preference for the ovulating female is triggered by subtle face shape differences | journal = Hormones and Behavior | volume = 62 | issue = 4 | pages = 413–17 | date = September 2012 | pmid = 22846725 | doi = 10.1016/j.yhbeh.2012.07.008 }}</ref> This idea is supported by another study, where a similar experiment was done. Men and women had to judge photographs of women's faces taken during their [[Fertility|fertile phase]]. They were all rated more attractive than during [[Luteal phase|non-fertile phase]]. There are some subtle visible cues to ovulation in women's faces, and they are perceived as more attractive, leading to the idea that it could be an adaptive mechanism to raise a female's mate value at that specific time (when probability of conception is at its highest).{{sfnp|Miller|Tybur|Jordan|2007}}

Women's attractiveness, as perceived by men and women, slightly differs across her menstrual cycle, being at peak when a woman is in her ovulation phase. Jones et al. (2008), focused on women's preferences for [[masculinity]], apparent health and self-resemblance and found that it varies across the cycle. They explained that the function of the effects of menstrual cycle phase on preferences for apparent health and self-resemblance in faces is to increase the likelihood of [[pregnancy]].<ref>{{cite journal | vauthors = Jones BC, DeBruine LM, Perrett DI, Little AC, Feinberg DR, Law Smith MJ | title = Effects of menstrual cycle phase on face preferences | url = https://archive.org/details/sim_archives-of-sexual-behavior_2008-02_37_1/page/78 | journal = Archives of Sexual Behavior | volume = 37 | issue = 1 | pages = 78–84 | date = February 2008 | pmid = 18193349 | doi = 10.1007/s10508-007-9268-y }}</ref>

Similarly, women prefer the scent of [[Facial symmetry|symmetrically faced]] men and men with masculine faces during fertile phases as well as stereotypical male displays such as social presence, and direct [[Intrasexual selection|intrasexual]] competitiveness.<ref>{{cite journal | vauthors = Gangestad SW, Simpson JA, Cousins AJ, Garver-Apgar CE, Christensen PN | title = Women's preferences for male behavioral displays change across the menstrual cycle | journal = Psychological Science | volume = 15 | issue = 3 | pages = 2030–7 | date = March 2004 | pmid = 15016293 | doi = 10.1111/j.0956-7976.2004.01503010.x }}</ref>

During the [[Ovulation|follicular]] phase (fertile), women prefer more masculine traits ([[testosterone (hormone)|testosterone]] dependent traits such as face shape) than when in non-fertile phase. Those findings have been found in the voice, showing that females' preferences for more masculine voices over feminine voices increase the fertile phase of the menstrual cycle.<ref name="Feinberg-2006">{{cite journal | vauthors = Feinberg DR, Jones BC, Law Smith MJ, Moore FR, DeBruine LM, Cornwell RE, Hillier SG, Perrett DI | title = Menstrual cycle, trait estrogen level, and masculinity preferences in the human voice | journal = Hormones and Behavior | volume = 49 | issue = 2 | pages = 215–22 | date = February 2006 | pmid = 16055126 | doi = 10.1016/j.yhbeh.2005.07.004 }}</ref>

But not only do females' preferences vary across cycle, their behaviours can vary as well. Effectively, men respond differently to women when they are on ovulatory cycle,{{sfnp|Miller|Tybur|Jordan|2007 }} because women act differently. Women in the ovulatory phase are flirtier with men showing [[Genetics|genetic]] fitness markers than in low fertile phase.<ref>{{cite journal | vauthors = Cantú SM, Simpson JA, Griskevicius V, Weisberg YJ, Durante KM, Beal DJ | title = Fertile and selectively flirty: women's behavior toward men changes across the ovulatory cycle | journal = Psychological Science | volume = 25 | issue = 2 | pages = 431–38 | date = February 2014 | pmid = 24335600 | doi = 10.1177/0956797613508413 }}</ref> It has been shown in some studies that women high in [[estrogen]] are generally perceived to be more attractive than women with low levels of estrogen, based on women not wearing make-up. High estrogen level women may also be viewed as healthier or to have a more [[Femininity|feminine]] face.<ref>{{cite journal | vauthors = Smith MJ, Perrett DI, Jones BC, Cornwell RE, Moore FR, Feinberg DR, Boothroyd LG, Durrani SJ, Stirrat MR, Whiten S, Pitman RM, Hillier SG | title = Facial appearance is a cue to oestrogen levels in women | journal = Proceedings.

Similarly, a study investigated the capacity of women to select high quality males based on their facial attractiveness. They found that facial attractiveness correlated with [[semen]] quality (good, normal, or bad depending on [[sperm]] morphology and motility). The more attractive a man's face is, linked to his sperm being of better quality.<ref>{{cite journal | vauthors = Soler C, Núñez M, Gutiérrez R, Núñez J, Medina P, Sancho M, Álvarez J, Núńez A | year = 2003 | title = Facial attractiveness in men provides clues to semen quality | url = https://archive.org/details/sim_evolution-and-human-behavior_2003-05_24_3/page/199 | journal = Evolution & Human Behavior | volume = 24 | issue = 3| pages = 199–207 | doi=10.1016/s1090-5138(03)00013-8| bibcode = 2003EHumB..24..199S }}</ref>

===Sexual ornamentation===
[[Sexual ornament]]s are seen in many organisms; in humans, females have sexual ornamentation in the form of breasts and buttocks. The physical attraction to sexual ornaments is associated with [[Gynoid fat distribution|gynoid fat]], as opposed to [[Android fat distribution|android fat]], which is considered unattractive.<ref>{{cite journal| vauthors = Singh D |date=1993|title=Adaptive significance of female physical attractiveness: Role of waist-to-hip ratio| url = https://archive.org/details/sim_journal-of-personality-and-social-psychology_1993-08_65_2/page/293 |journal=Journal of Personality and Social Psychology|doi=10.1037/0022-3514.65.2.293 |pmid=8366421|volume=65|issue=2|pages=293–307 }}</ref> In human females, proximate causes of the development of sexual ornaments are associated with the predominance of estrogen in puberty. The activation of [[estrogen receptor]]s around the female skeletal tissue causes gynoid fat to be deposited in the breasts, buttocks, hips and thighs, producing an overall typical female body shape.<ref>{{cite journal | vauthors = Scheaefer K, Fink B, Grammer K, Mitteroecker P, Gunz P, Bookstein FL |date=2006|title=Female appearance: facial and bodily attractiveness as shape|journal=Psychology Science}}</ref> Specifically, female breasts are considered more attractive when symmetrical, rather than asymmetrical,<ref>{{cite journal | vauthors = Dixson BJ, Vasey PL, Sagata K, Sibanda N, Linklater WL, Dixson AF | title = Men's preferences for women's breast morphology in New Zealand, Samoa, and Papua New Guinea | url = https://archive.org/details/sim_archives-of-sexual-behavior_2011-12_40_6/page/1271 | journal = Archives of Sexual Behavior | volume = 40 | issue = 6 | pages = 1271–79 | date = December 2011 | pmid = 20862533 | doi = 10.1007/s10508-010-9680-6 }}</ref> as this is thought to reflect good [[Ontogeny|developmental stability]].<ref>{{cite journal | last1=Thornhill|first1=Randy|last2=Grammer|first2=Karl | name-list-style = vanc |date=1999|title=The Body and Face of Woman: One Ornament That Signals Quality?| url=https://archive.org/details/sim_evolution-and-human-behavior_1999-03_20_2/page/105|journal=Evolution and Human Behavior|volume=20|issue=2|pages=105–20|doi=10.1016/S1090-5138(98)00044-0|bibcode=1999EHumB..20..105T }}</ref>

Sexual ornaments are considered attractive features as they are thought to indicate high mate value, fertility,<ref>{{cite journal | vauthors = Jasieńska G, Ziomkiewicz A, Ellison PT, Lipson SF, Thune I | title = Large breasts and narrow waists indicate high reproductive potential in women | journal = Proceedings. Biological Sciences | volume = 271 | issue = 1545 | pages = 1213–17 | date = June 2004 | pmid = 15306344 | pmc = 1691716 | doi = 10.1098/rspb.2004.2712 }}</ref> and the ability to provide good care to offspring. They are [[Sexual selection|sexually selected]] traits present for the purpose of [[Signalling theory|honest signalling]] and capturing the visual attention of the opposite sex, most commonly associated with women capturing the visual attention of men. It has been proposed that these ornaments have evolved in order to advertise personal quality and [[reproductive value (social psychology)|reproductive value]].<ref>{{cite journal | vauthors = Marlowe F | title = The nubility hypothesis: The human breast as an honest signal of residual reproductive value | journal = Human Nature | volume = 9 | issue = 3 | pages = 263–71 | date = September 1998 | pmid = 26197484 | doi = 10.1007/s12110-998-1005-2 }}</ref> Honest signalling with sexual ornaments is associated with ultimate causation of these evolved traits. The evolution of these ornaments is also associated with female-female competition in order to gain material benefits provided by resourceful and high status males.{{sfnp|Wang et al.|2015}} In humans, once these sexual ornaments develop, they are permanent. It is thought that this is associated with the long-term pair bonding humans engage in; human females engage in extended sexual activity outside of their fertile period.<ref>{{cite journal | vauthors = Grebe NM, Gangestad SW, Garver-Apgar CE, Thornhill R | title = Women's luteal-phase sexual proceptivity and the functions of extended sexuality | url = https://archive.org/details/sim_psychological-science_2013-10_24_10/page/2106 | journal = Psychological Science | volume = 24 | issue = 10 | pages = 2106–10 | date = October 2013 | pmid = 23965377 | doi = 10.1177/0956797613485965 }}</ref> This relates to another ultimate cause of sexual ornaments with function in obtaining non-genetic material benefits from males. In other animal species, even other primate species, these advertisements of reproductive value are not permanent. Usually, it is the point at which the female is at her most fertile, she displays [[sexual swelling]]s.<ref>{{cite journal | vauthors = Domb LG, Pagel M | title = Sexual swellings advertise female quality in wild baboons | journal = Nature | volume = 410 | issue = 6825 | pages = 204–06 | date = March 2001 | pmid = 11242079 | doi = 10.1038/35065597 | bibcode = 2001Natur.410..204D }}</ref>

[[Adolescence]] is the period of time whereby humans experience [[puberty]], and experience anatomical changes to their bodies through the increase of sex hormones released in the body. Adolescent exaggeration is the period of time at which sexual ornaments are maximised, and peak gynoid fat content is reached.{{sfnp|Wang et al.|2015}} In human females, the mean age for this is approximately 16 years. Female breasts develop at this stage not only to prepare for reproduction, but also due to competition with other females in displaying their reproductive value and quality to males.{{sfnp|Wang et al.|2015}}

==Neural correlates of perceiving attractiveness==
Most studies of the brain activations associated with the perception of attractiveness show photographs of faces to their participants and let them or a comparable group of people rate the attractiveness of these faces.

Some evolutionary psychologists, including David Buss, have argued that this long-term relationship difference may be a consequence of ancestral humans who selected partners based on [[secondary sexual characteristics]], as well as general indicators of fitness which allowed for greater reproductive success as a result of higher fertility in those partners,<ref>{{cite book | vauthors = Symons D | year = 1995 | chapter = Beauty is in the adaptations of the beholder: the evolutionary psychology of human female sexual attractiveness. | title = Sexual Nature, Sexual Culture | url = https://archive.org/details/sexualnaturesexu0000unse | series = Chicago Series on Sexuality, History, and Society | veditors = Abramson PR, Pinkerton SD | pages = [https://archive.org/details/sexualnaturesexu0000unse/page/80 80]–119 | location = Chicago | publisher = Univ.

According to Bonnie Adrian, Taiwanese brides place great importance on physical attractiveness for their wedding photographs. These brides go through hours of makeup to transform themselves into socially constructed beauty. Adrian notes that female beauty standards and practices in Taiwan are quite different from those found in the West. Women in Taiwan tend to avoid tanning, while Taiwanese women with tanned skin tones would be considered the ideal in the Western world.<ref>{{cite book | last=Adrian | first=Bonnie | title=Framing the Bride: Globalizing Beauty and Romance in Taiwan's Bridal Industry | publisher=University of California Press | year=2003 | isbn=978-0-520-23834-3 | page=[https://books.google.com/books?id=saYwDwAAQBAJ&pg=PA165 165]}}</ref>

According to strategic pluralism theory, men may have correspondingly evolved to pursue reproductive strategies that are contingent on their own physical attractiveness. More physically attractive men accrue reproductive benefits from spending more time seeking multiple mating partners and relatively less time investing in offspring. In contrast, the reproductive effort of physically less attractive men, who therefore will not have the same mating opportunities, is better allocated either to investing heavily in accruing resources, or investing in their mates and offspring and spending relatively less time seeking additional mates.<ref>{{cite journal | vauthors = Frederick DA, Haselton MG | title = Why is muscularity sexy?

==Facial similarity and racial preferences==
{{See also|Race and sexuality}}

Research has suggested that people give high attractiveness ratings to same-sex people who [[Interpersonal attraction#Similarity (like-attracts-like)|look like them]], but only in a nonsexual context. On the other hand, people generally do not find similar-looking people of the opposite sex to be sexually attractive. It is theorised that people may prefer sexual partners who look different from them, which is consistent with a pattern of [[inbreeding avoidance]].<ref>{{cite journal |last1=Little |first1=Anthony C. |last2=Jones |first2=Benedict C. |last3=DeBruine |first3=Lisa M. |title=Facial attractiveness: evolutionary based research |journal=Philosophical Transactions of the Royal Society B: Biological Sciences |date=12 June 2011 |volume=366 |issue=1571 |pages=1638–1659 |doi=10.1098/rstb.2010.0404 |pmid=21536551 |pmc=3130383 |quote=Male and female 'siblings' of both male and female participants were manufactured using computer-graphic methods detailed in DeBruine et al.

However, there was no such opposite-sex bias when the same faces were judged for averageness. This own-sex bias in preferences for self-resemblance indicates that, while self-resemblance is attractive in an exclusively prosocial (i.e. nonsexual) context, it is less attractive in a potential mating context. Stronger attraction to cues of kinship in own-sex faces than in opposite-sex faces is likely to promote prosocial behaviour towards own-sex kin, while minimizing occurrences of inbreeding with opposite-sex kin. }}</ref><ref>{{cite journal | vauthors = DeBruine LM |title=Resemblance to self increases the appeal of child faces to both men and women |journal=Evol Hum Behav |volume=25 |issue=3 |pages=142–54 |date=May 2004 |doi=10.1016/j.evolhumbehav.2004.03.003|bibcode=2004EHumB..25..142D }}</ref><ref>{{cite journal | vauthors = DeBruine LM | title = Trustworthy but not lust-worthy: context-specific effects of facial resemblance | journal = Proceedings.

In contrast, a 2013 Australian study on facial attractiveness with Asian and White participants found that Asian and White women's faces were not different in attractiveness overall, although a slight own-race bias was observed. However, when rating composite faces (the average of many faces, grouped by race, as opposed to real faces), all participants rated the composite faces more highly and rated White women's composite faces the highest.

A 2008 American study on female facial attractiveness with majority White participants (with a significant proportion of Asian, and few Black, Hispanic, or Middle-Eastern participants) found that White women's faces were rated most attractive. The study showed gradations of computer-generated racial mixes to the participants in increments of one-quarter. The top three rated faces were 100% White, 75% White 25% Black, and 75% White 25% Asian.

A 2012 study using Black and Caucasian subjects found that inter-ethnic and intra-ethnic differences in perceived male facial masculinity have no impact on attractiveness, and that skin colour plays a more important role in attractiveness assessments of male faces within groups, but not between groups as a health signal.<ref>{{cite journal| vauthors = Stephen ID, Scott IM, Coetzee V, Pound N, Perrett DI, Penton-Voak IS |date=July 1, 2012|title=Cross-cultural effects of color, but not morphological masculinity, on perceived attractiveness of men's faces |journal=Evolution and Human Behavior |volume=33 |issue=4 |pages=260–67 |doi=10.1016/j.evolhumbehav.2011.10.003 |bibcode=2012EHumB..33..260S |hdl=2263/19120 |url=http://bura.brunel.ac.uk/handle/2438/7032 |hdl-access=free }}</ref>

== Group attractiveness effect ==
{{Main|Group attractiveness effect}}

The [[group attractiveness effect]] is where a group's overall attractiveness rating is higher than the mean of each individuals' attractiveness rating. This occurs because people selectively attend to the most attractive group members<ref>{{cite journal |last1=Maner |first1=Jon K. |last2=Kenrick |first2=Douglas T. |last3=Becker |first3=D. Vaughn |last4=Delton |first4=Andrew W. |last5=Hofer |first5=Brian |last6=Wilbur |first6=Christopher J. |last7=Neuberg |first7=Steven L. |title=Sexually Selective Cognition: Beauty Captures the Mind of the Beholder |journal=Journal of Personality and Social Psychology |date=2003 |volume=85 |issue=6 |pages=1107–1120 |doi=10.1037/0022-3514.85.6.1107 |pmid=14674817 }}</ref> and thus they get the most attention. Men selectively attend to attractive people more than women, it has been suggested that this could be because men are less invested in their [[offspring]], so they are less choosy when it comes to sexual partners, and therefore they are more easily attracted. As a result of selective attention, people end up giving a group rating which is biased as the rating focuses mainly on the attractive members and ignores the less attractive members. So the overall attractiveness rating is skewed towards more attractive. The group attractiveness effect was investigated in a study which got participants to rate the physical attractiveness of a group of females as a whole, individually in a group, and individually on their own.<ref>{{cite journal |last1=van Osch |first1=Yvette |last2=Blanken |first2=Irene |last3=Meijs |first3=Maartje H.

The group attractiveness effect has been replicated with males as the main group and also with a group of both males and females. This effect may not be demonstrated across all cultures because the sample only contained Dutch university students.

==Social effects==
Perceptions of physical attractiveness contribute to generalised assumptions based on those attractions. Individuals assume that when someone is beautiful, then they have many other positive attributes that make the attractive person more likeable.{{sfnp|Barelds-Dijkstra|Barelds|2008}} This is referred to as the [[halo effect]], also known as the 'beautiful-is-good' effect.{{sfnp|Barelds-Dijkstra|Barelds|2008}} Across cultures, what is beautiful is assumed to be good; attractive people are assumed to be more extroverted, popular, and happy.

In developed western societies, women tend to be judged for their physical appearance over their other qualities and the pressure to engage in beauty work is much higher for women than men.

However, attractiveness varies by society; in ancient China [[foot binding]] was practiced by confining young girls' feet in tightly bound shoes to prevent the feet from growing to normal size causing the women to have an attractive "lotus gait".{{cn|date=October 2025}}

People make judgments of physical attractiveness based on what they see, but also on what they know about the person. Specifically, perceptions of beauty are malleable such that information about the person's personality traits can influence one's assessment of another person's physical beauty. A 2007 study had participants first rate pictures for attractiveness. After doing distracting math problems, participants saw the pictures again, but with information about the person's personality. When participants learned that a person had positive personality characteristics (e.g., smart, funny, kind), that person was seen as more physically attractive.<ref>{{cite journal |title=Personality goes a long way: The malleability of opposite-sex physical attractiveness | vauthors = Lewandowski Jr GW, Aron A, Gee J |journal=Personal Relationships |volume=14 |issue=4 |year=2007 |pages=571–585 |doi=10.1111/j.1475-6811.2007.00172.x }}</ref> Conversely, a person with negative personality characteristics (e.g., materialistic, rude, untrustworthy) was seen as less physically attractive. This was true for both females and males.

Physical attractiveness can have various social effects.

It is important to note that other factors such as self-confidence may explain or influence these findings as they are based on self-reported attractiveness as opposed to any sort of objective criteria; however, as one's self-confidence and [[self-esteem]] are largely learned from how one is regarded by their peers while maturing, even these considerations would suggest a significant role for physical appearance.

Concern for improving physical attractiveness has led many persons to consider alternatives such as [[cosmetic surgery]]. It has led scientists working with related disciplines such as [[computer imaging]] and [[mathematics]] to conduct research to suggest ways to surgically alter the distances between facial features in order to make a face conform more closely to the "agreed-upon standards of attractiveness" of an ideal face by using algorithms to suggest an alternative which still resembles the current face.{{sfnp|Kershaw|2008}} One research study found that cosmetic surgery as a way to "boost earnings" was "not profitable in a monetary sense."{{sfnp|Jayson|2011}} Some research shows that physical attractiveness has a marginal effect on happiness.<ref>{{cite journal |last1=Diener |first1=Ed |last2=Wolsic |first2=Brian |last3=Fujita |first3=Frank |title=Physical attractiveness and subjective well-being |journal=Journal of Personality and Social Psychology |date=July 1995 |volume=69 |issue=1 |pages=120–129 |doi=10.1037/0022-3514.69.1.120 }}</ref>
