Young Black Haired Girl Wet Wearing Various Swimsuits

Alternatives to swimsuits
Some women prefer to engaging in water or sun activities with the torso uncovered. The practice is often described as "toplessness" or "topfreedom". Some people prefer not to wear any swimsuit when engaging in such activities. In some places around the world, nude beaches have been set aside for people who choose to engage in normal beach activities in the nude.
As an alternative to a swimsuit, some people wear trousers, underpants or a T-shirt either as a make-shift swimsuit or because they prefer regular clothes over swimsuits. In some countries, such as Thailand, swimming in regular clothes is the norm while swimsuits are rare. At beaches, this may be more accepted than at swimming pools, which tend not to permit the practice because underwear is unlined, may become translucent, and may be perceived as unclean.
