Long sleeved onesie with contrasting colored detailing for newborn baby boy. This design features a t-shirt with a round neck collar and an overlapping, non-detachable dungaree onesie. There are snap-button fasteners around the crotch and on the back. This onesie is made from soft, stretchy cotton fabric. For this item, the bigger sizes (from 4-6 to 12 months) do not have feet, making it easier for your baby to move around comfortably when wearing the onesie.
