A swimsuit, bathing suit, swimming costume, bathing costume, swimming suit, swimmers, swimming togs, bathers, cossie, or swimming trunks for men, is an item of clothing designed to be worn by people 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. Different types are worn by men, women, and children. 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. Swimwear for men usually exposes the chest, which women do not usually do.
