Looooove. My 3.5 year old daughter is tall (40 inches) and average weight (33 pounds). Based on other reviews I bought this beautiful ballet dress a size 5 and it fits perfectly. Nothing is lost anywhere, but there is definitely room for improvement. Pink is VERY tough. They didn't have a pink ballet for their size. i still like it I love that the upper is made of soft t-shirt-like fabric. I love how fluffy it is and so does my daughter!
