A leotard is an item of clothing usually worn for activities such as training or performing for gymnastics, ballet, or aerobics. Generally a leotard has leg-holes, a neck-hole, and it may or may not have sleeves (in absence of sleeves, spaghetti straps or a tank-top style cut is present.) Akin to a one-piece swimsuit, but to be worn out of the water. It is made of spandex (and occasionally other fabrics) for the purpose of exposing one's body to scrutiny while other people are watching. Constant wearing of leotards under the observation of other people may be a reason many girls have eating disorders.
