This is a cute costume for Halloween or pretend play. The costume consists of a one piece gown with 2 gloves. The gown fits most kids who are 3 to 4 feet in height. The gloves are 9 inches long. They were a little big for my 7 year old but she was still able to wear them. The material is somewhat sheer so clothing needs to be worn underneath. My daughter wore a black long sleeve body suit and black leggings under the gown.The gown has slits up both sides so it is not constricting and allows the child to move freely. I was a bit disappointed that it doesn't glow in the dark as the video showed on the product page but it is still a good costume for the price.
