Swimsuit or swimwear

A swimsuit, bathing suit, swimming costume, tog, bathers, or cossie (short for "costume") is an item of clothing designed to be worn by men, women or children while they are engaging in a water-based activity or water sports, such as swimming, water polo, diving, surfing, water skiing, or during activities in the sun, such as sun bathing.
A swimsuit can be worn as an undergarment in sports that require a wetsuit such as water skiing, scuba diving, surfing, and wakeboarding. Swimsuits are also worn when there is a need to display the body, as in the case of beauty pageants or bodybuilding contests. Glamour photography and magazines like the annual Sports Illustrated Swimsuit Issue feature models and sports personalities in swimsuits.
There is a very wide range of styles of modern swimsuits, which vary in relation to body coverage and materials. The choice of style of swimsuit is dependent on current fashions and community standards of modesty, as well as on personal preferences.
Swimsuit styles
In western culture, men's swimsuit styles include boardshorts, jammers, swim trunks, briefs or "speedos", thongs, and g-strings, in order of decreasing lower body coverage.
Women's swimsuits are generally described as one-piece, bikinis, or thongs. While they go through many trends in pattern, length and cut there is not much modification to the original variety of suit.[1] A recent innovation is the burqini, favored by Muslim women, which covers the whole body and head (but not face) in a manner similar to a diver's wetsuit. These are an updated version of full-body swimwear, which has been available for centuries, but conforms with Islam's traditional emphasis on modest dress. In Egypt, the term "Sharia swimsuit" is used to describe full-body swimwear
