Topfreedom is a cultural and political movement seeking changes in laws to allow women to be topless in public places where men are permitted to be barechested, as a form of gender equality. Specifically, the movement seeks the repeal or overturning of laws which restrict a woman's right not to have her chest covered at all times in public.
In addition, topfreedom advocates seek allowing nursing mothers to openly breastfeed in public.
Cleavage is the narrow depression or hollow between the breasts of a woman. The superior portion of cleavage may be accentuated by clothing such as a low-cut neckline that exposes the division, and often the term is used to describe the low neckline itself, instead of the term décolletage. Joseph Breen, head of the U.S. film industry's Production Code Administration, coined the term in its current meaning when evaluating the 1943 film The Outlaw, starring Jane Russell. The term was explained in Time magazine on August 5, 1946. It is most commonly used in the parlance of Western female fashion to refer to necklines that reveal or emphasize décolletage (display of the upper breast area).
The visible display of cleavage can provide erotic pleasure for those who are sexually attracted to women, though this does not occur in all cultures. Explanations for this effect have included evolutionary psychology and dissociation from breastfeeding. Since at least the 15th century, women in the Western world have used their cleavage to flirt, attract, make political statements (such as in the Topfreedom movement), and assert power. In several parts of the world, the advent of Christianity and Islam saw a sharp decline in the amount of cleavage which was considered socially acceptable. In many cultures today, cleavage exposure is considered unwelcome or is banned legally. In some areas like European beaches and among many indigenous populations across the world, cleavage exposure is acceptable; conversely, even in the Western world it is often discouraged in daywear or in public spaces. In some cases, exposed cleavage can be a target for unwanted voyeuristic photography or sexual harassment.
Go Topless Day (variously known as National Go Topless Day, International Go Topless Day) is an annual event held in the United States, Canada, and Switzerland to support the right of women to go topless in public on gender-equality grounds. In states where women have that right, topfreedom laws are celebrated, and protests are held in states where topless women are prohibited.
The relationship between nudity and sexuality can be complicated. When people are nude, this often leads to sexual arousal, which is why indecent exposure is often considered a crime. There are also social movements to promote a greater degree of nudity, such as the topfreedom movement to promote female toplessness, as well as the movement to promote breastfeeding in public. Furthermore, some psychiatric disorders that can lead to greater nudity include exhibitionistic disorder, voyeuristic disorder, and gymnophobia.
Toplessness refers to the state in which a woman's breasts, including her areolas and nipples, are exposed, especially in a public place or in a visual medium. The male equivalent is known as barechestedness.
Social norms around toplessness vary by context and location. Many indigenous societies consider breast exposure to be normal and uncontroversial. At specific beaches and resort destinations, notably in Europe and Australia, girls and women may sunbathe topless either by statute or by custom. However, in most countries, norms of female modesty require girls and women to cover their breasts in public, and many jurisdictions prosecute public toplessness as indecent exposure. The topfreedom movement opposes such laws on the grounds of gender equality.
