is a skin-tight one-piece garment
with long sleeves made famous by the French acrobatic performer Jules Léotard
), about whom the song "The daring young man on the Flying Trapeze" was written.
The name "leotard" was applied retroactively; Léotard apparently called the garment a "maillot".
Leotards are worn by acrobats, gymnasts, dancers and circus performers, as well as others. They are often worn together with tights.
Leotards have scoop necklines - entry is through the neck. (Compare bodysuit).
A leotard that is extended to include long legs, removing the need for tights, is known as a unitard.
Leotards can also be worn as lingerie and are eroticised by some people, often as part of a wider spandex fetishism.
