It has been proposed by scientists that the evolutionary reason for the female body shape is due in part to this sexual selection.Sex-typical body shapes (a man's muscular physique and a woman's hourglass figure) are an outcome of evolutionary adaptation for reproductive fitness because they convey information about gene quality, health and fertility, which are important elements for mate ...
The waist is typically smaller than the bust and hips, unless there is a high proportion of body fat distributed around it. How much the bust or hips inflect inward, towards the waist, determines a woman's structural shape. The hourglass shape is present in only about 8% of women. [30]
Both men and women judge women with smaller waist-to-hip ratios more attractive. [254] Ethnic groups vary with regard to their ideal waist-to-hip ratio for women, [ 255 ] ranging from 0.6 in China, [ 256 ] to 0.8 or 0.9 in parts of South America and Africa, [ 257 ] [ 258 ] [ 259 ] and divergent preferences based on ethnicity, rather than ...
Variables such as posture significantly influence the measurement of the waist, and therefore any measurements for a group need to maintain a constant posture between the subjects. [6] Waist size (waist circumference) is an indicator of abdominal obesity and is one of the criteria for diagnosing the metabolic syndrome. Excess abdominal fat is a ...
Similarly, a 5'4" woman's waist should measure 32 inches. An increase of as many as seven inches can trim more than one and a half years off his or her life.
The buttocks are formed by the masses of the gluteal muscles or "glutes" (the gluteus maximus muscle and the gluteus medius muscle) superimposed by a layer of fat.The superior aspect of the buttock ends at the iliac crest, and the lower aspect is outlined by the horizontal gluteal crease.
While female buttocks are often eroticized in heterosexual erotica, men's buttocks are considered erogenous by many women, and are also eroticized in male homosexuality which often centers on anal intercourse. [11] [12] Historically, they are also portrayed in sculpture and other image art with a frequency equalling that of the females.
Unlike men's briefs, this style is usually lower cut. Boyshorts often cover most of the buttocks. [7] [8] Briefs rise to the waist, or just below the navel, and have full coverage in the rear. Classic briefs have the waistband sitting very high on the waist. The leg holes are small so the underwear cover as much area between waist and thigh as ...
