"I really set my expectations low with this costume in a bag order, but it really exceeded my expectations. There is a lot of detail to this costume that would have taken forever (and been quite expensive) to try to do at home. Sizing: I have a slender 6 year old and thought we needed the sz 4-6 but we went with the 8-10 which I was certain was going to fall right off her, but it fits surprisingly well. The waist is easy to roll."
