A leotard (ˈliːətɑːrd) is a unisex skin-tight one-piece garment that covers the torso from the crotch to the shoulder. The garment was made famous by the French acrobatic performer Jules Léotard (1838–1870). There are sleeveless, short-sleeved, and long-sleeved leotards. A variation is the unitard, which also covers the legs.
Leotards are worn by acrobats, gymnasts, dancers, figure skaters, athletes, actors, wrestlers, and circus performers both as practice garments and performance costumes. They are often worn with ballet skirts on top and tights or sometimes bike shorts as underwear. As a casual garment, a leotard can be worn with a belt; it can also be worn under overalls or short skirts.
Leotards are entered by stepping into the legs and pulling the sleeves over the shoulders. 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.
Leotards are used for a variety of purposes, including yoga, exercise, dance (particularly for ballet and/or modern), as pajamas, for additional layered warmth under clothing, and for recreational and casual wear. They may form a part of children's dressing up and play outfits and can also be worn as a top.
Leotards are commonly worn in figure skating, postwar modern dance, acrobatic rock'n'roll, traditional ballet and gymnastics, especially by young children. Practice leotards and those worn in podium training sessions are usually sleeveless. Female competition garments for gymnastics and skating are almost always long-sleeved, while male competition leotards may be sleeved or sleeveless, the latter more common in gymnastics, the former in figure skating. Leotards come in many styles — either with a full seated bottom or as a thong or T-front thong for maximum comfort and avoidance of visible panty lines when worn under leggings or tights.
The first known use of the name leotard came only in 1886, many years after Jules Léotard's death.
