Construction is a boys favorite! The orange and white gingham jon jon is handsmocked at the chest with a dozer, dump truck and some rocks. The arm holes are L shaped which allow some extra breathing and could be dressed up with a shirt underneath. There is two buttons on each shoulder to get over a childs head and snaps along the inside of the legs to accomodate diaper changes. This adorable jon jon is 55% cotton and 45% polyester.
