These are really beautiful dresses! I brought them for my daughters. I sized up and they fit nicely. The material feels solid and comfortably heavy - not flimsy at all!

They seem to be meant to be around knee length. I prefer slightly longer, so sizing up worked. But I would have needed to size up anyways for the waist (average weight).

I wasn't impressed by the belt, but the dress can be worn either with or without.
