Bought size 7 for 48 inch, 52 lb child. Fits well all around. Dress feels well made, with the exception of the fragile top layer. The top layer extends beyond the other skirt layers by an inch or two. Will tear easily.  The first thing that almost happened was it being stepped on. I will be trimming top layer to fall in line with the other layers. Would recommend to other shoppers! Great dress for twirling.
