Swimsuit

Special swimsuits for competitive swimming, designed to reduce skin drag, can resemble unitards. For some kinds of swimming and diving, special bodysuits called diveskins are worn. These suits are made from spandex and provide little thermal protection, but they do protect the skin from stings and abrasion. Most competitive swimmers also wear special swimsuits including partial and full bodysuits, racerback styles, jammers and racing briefs to assist their glide through the water and gain speed advantages (see competitive swimwear).
Swimming without a bathing suit is a form of social nudity. Special nude beaches may be reserved for nude sunbathing and swimming. Swimming in the nude is also known by the slang term "skinny-dipping". As an alternative to a bathing suit some people use their trousers, underpants or T-shirt as a make-shift swimsuit. At beaches norms for this tend to be more relaxed than at swimming pools, which tend not to permit this because underwear is unlined, may become translucent, and may be perceived as unclean.
Swimsuits are also worn for the purpose of body display in beauty pageants. Magazines like Sports Illustrated's annual "swimsuit issue" feature models and sports personalities in swimsuits.
