My daughter is 8 1/2 and has outgrown all the size 8 pants but all the size 10s from every other manufacturer were too big! What happened to size 9 anyway? Why doesn’t anyone make size 9 pants for girls. Anyway, the size 10s in this brand fit my daughter perfectly! If your daughter is on the chunkier side, and the 10s in other brands fit, these may be too small. These fit my slim to normal sized 8 year old perfectly.
