Hello and welcome back...
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 (1842–1870).
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 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.
