I love these socks. I ordered for my granddaughter. She is 6 years old, wears a 7 and wears a size 6-8. But when the order for size 6-8 came in, two more orders came in for other socks. For the same size, they were SMALL compared to the others (which fit btw). They might fit, but they would need to be stretched, and where would I be with brand new socks that only last a few months and not the ones that fit. and can grow into this, which will last for many months. All in all these are great and adorable socks so I immediately turned around and ordered the next size up. (9-10) I hope they fit. So do yourself a favor and order one size larger than necessary.
