One-pieces and Onesies® are also called bodysuits. The term is most often used to describe a short-sleeved bodysuit that does not cover the baby's legs, but it also can refer to versions with long sleeves and long legs. Onesies® can be used as a complete outfit, as a t-shirt, or as an undergarment. Onesies® and one-piece bodysuits range in style from simple, white, undergarment versions to colorful, patterned and embroidered types.
