A leotard is a unisex skin-tight one-piece garment that covers the torso but leaves the legs free. It was made famous by the French acrobatic performer Jules Léotard (1838–1870).
Leotards are worn by acrobats, gymnasts, dancers, figure skaters, athletes, actors, and circus performers both as practice garments and performance costumes. They are often worn together with ballet skirts on top and tights[1] or sometimes bike shorts as underwear. There are sleeveless, short-sleeved and long-sleeved leotards. A variation is the unitard, which also covers the legs. As a casual garment, a leotard can be worn with a belt,it can also more commonly worn under overalls or short skirts
Leotards are entered through the neck, in contrast to bodysuits which generally have snaps at the crotch, allowing the garment to be pulled on over the head. Scoop-necked leotards have wide neck openings and are held in place by the elasticity of the garment. Others are crew necked or polo necked and close at the back of the neck with a zipper or snaps.
