A one-piece swimsuit most commonly refers to swimwear worn primarily by women and girls when swimming in the sea or in a swimming pool, playing water polo, or for any activity in the sun, such as sun bathing. Today, the one-piece swimsuit is usually a skin-tight garment that covers the torso, although some designs expose the back or upper chest.
