Leotards are a type of clothing typically worn by dancers, gymnasts, and other athletes. They are form-fitting garments that cover the torso and legs, and often have long sleeves and a high neckline. The term 'leotard' is derived from the name of the French acrobat Jules Leotard, who popularized the garment in the late 19th century. TIGHTS are a type of clothing similar to leotards, but they are usually made of a thinner material and cover the entire leg. They are often worn as part of a dance or gymnastics outfit.
