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.

Before the popularity of the two-piece swimsuit, and then the bikini, virtually all women's swimwear completely covered at least the wearer's torso, and men also wore similar swimsuits. While the bikini has increasingly found popular acceptance since the 1960s, the one-piece swimsuit has maintained a place on beaches to this day.^[1]
