My daughter is a normal size 10, she is tall and thin and she is 7 years old when she tried on this dress it was too long for her. The fit on the side was fine as it was too long to drag across the floor. I've been waiting for a refund for over a month now. Consider going down the size 4-6 as I order a size 12 for my 7 year old daughter who was too long and then I order a size 4 which fits her length not width.
