"I bought a size Small for my 5 year old. She loves it. The costume is cute, but it is really short. It is necessary to wear tights with it. Also, the colors on the hat don't really match the colors of the skirt, but it's not so bad that most will notice, especially at night. I did shape a piece of foam paper into a cone and pin it to the hat so it would stay up. Overall, a cute costume, but the color difference made me rate it a 4 rather than a 5."
