An infant bodysuit, also known as a onesie, is a t-shrit-like garment worn by a baby that snaps or fastens in the crotch area for easy dressing and changing. A onesie can be worn as an undergarment or as an outershirt. Baby SuperMall has a large selection of long sleeve onesies, short sleeve onesies, sleeveless onesies, and basic onesies.
