Workout wear typically consists of items such as leotards, sweats, and legwarmers. A leotard is a tight-fitting garment that covers the torso and legs, usually made of spandex or nylon. Sweats are loose-fitting pants, often made of cotton, that are designed to keep the wearer warm during exercise. Legwarmers are knitted tubes of fabric that are worn over the legs to keep them warm during exercise. All of these items are popular choices for workout wear.
