Breasts Cleavage Girl

Evolutionary psychologists theorize that humans' permanently enlarged breasts, in contrast to other primates' breasts, which only enlarge during ovulation, allowed females to "solicit male attention and investment even when they are not really fertile", though Morris notes that in recent years there has been a trend toward reversing breast augmentations. Several brassiere manufacturers, among them Wonderbra and Victoria's Secret, have become known for marketing products that enhance the décolletage. On the first Friday of April in South Africa, Wonderbra sponsors a National Cleavage Day. According to social historian David Kunzle, waist confinement and the décolletage are the primary sexualization devices of Western costume. Art historian James Laver argued that the changing standards of revealing the cleavage is more prominent in the evening dress than the day dress of women in the Western world.
Cultural aspects
In Western and some other societies, there are differences of opinion as to how much cleavage exposure is acceptable in public. In contemporary Western society, the extent to which a woman may expose her breasts depends on social and cultural context. Women's swimsuits and bikinis commonly reveal the tops and sides of the breasts. Displaying cleavage is considered permissible in many settings, and is even a sign of elegance and sophistication on many formal social occasions, but it may be prohibited by dress codes in settings such as workplaces, churches and schools, where any display of the female breast may be considered inappropriate. Showing the nipples or areolae is almost always considered toplessness or partial nudity.
