Size 3. Awesome Elephant body costume. Looks great on, very comfortable to wear plus it's warm and cozy. Zips up and the Elephant "feet" sit perfectly ontop of your childs shoes. (looks so darn cute) Perfect for cold Halloween trick or treat weather, fits over clothing or jacket. Our little one was always warm. I cannot say enough about this costume, it's a high quality item. In perfect condition, like brand new. Comes from an extremely clean home, no pets and non-smoking environment.
