An infant bodysuit is a garment designed to be worn by infants much like a T-shirt; they are distinguished from T-shirts by an extension below the waist, with snaps or Velcro that allow it to be closed over the crotch. The purpose of the opening at the crotch is to facilitate access to the infant's diaper. Like T-shirts, infant bodysuits come in a wide variety of designs and may be worn as undergarments or as outer shirts.
