There's something odd about becoming an adult baby, but forget all that when you go in this big baby costume! This adult baby boy plus size costume includes a baby blue jumpsuit, bib, and bonnet. The jumpsuit is made of polyester and is soft to the touch. The jumpsuit features a white neckline and ties close in the back. The back is open so wearing a shirt is recommended. The bib is white and ties behind the neck with white string. The bonnet is baby blue and features lace detailing throughout the front. The bonnet ties underneath the neck with white string. We have a womens plus size pink version, too!
