I chose the 8-12 year old option for these socks and put them in gift bags for my daughters party in August. Last month one of the mothers admitted that the socks are small. I had no idea! Confused for sure, and since I still had a few in my bag I checked again. Naturally. They have almost no stretch and barely fit my 9 year old! Cute socks, but check the size right away. They are more suitable for 5 year olds.
