"This is a great costume for a young boy who wants to have a boyish costume, but doesn't want to wear a scary costume for Halloween. This runs SMALL so beware when ordering! The size states 4-6...no way is that accurate! My son is very tiny 4 yr old who wears size 3 in clothing. This barely fits him in the crotch and behind area. Be mindful when ordering, this size costume that states 4-6 is more appropriately sized for a child who wears a 3T. But it is very cute. The material is very thin. The child will need to layer clothing under it."
