These are exactly true to size. I know our kids are all different sizes so let me try and give you some sizing comparisons with my kid and the dresses. My daughter is 4’ 10”, she is ten, and she weighs about 75 pounds. I ordered the size 9-10 because I figured the 10-13 would be more for a 13 year old than a 10 year old. I was correct. She loves them. We got two.
