"I purchased this costume for my 4 year old for Halloween. He looks adorable in it. The sizes do run small so make sure you take that into consideration before purchasing a size. My son is on the smaller size for his age and the 4-6 size fits perfectly. My only complaint about the costume is the ears. They do NOT stand up like in the picture. I think I have to install some kind of wire in them to make them stand up. But over all, it is adorable."
