This is a set of three baby rompers. The two bear-patterned rompers can be converted from a dress type to a pants type by changing the way the buttons are fastened at the crotch, making them comfortable for the baby. The light striped romper in the fourth photo is made of a velour-like material, so it should keep the baby warm. One child used these for about three months, but they are in good condition with no noticeable stains and can still be worn. Thank you.
