A leotard is a form-fitting one-piece garment that covers the torso, arms and legs. It was originally designed for use in gymnastics to allow greater freedom of movement during exercise. The name comes from French trapeze artist Jules Léotard who popularized the style in the 19th century. Today, leotards are also used in other activities such as dance and aerobics, but they have also become a fashionable item for everyday wear due to their versatility and comfort.
