We love these socks - I'm ordering another set in the process - as others have written they are shrinking so one size larger! My daughter is 4 1/2 and I'm buying her a 6-8 - although in another 6 months I may even be buying a 9-11. The colors are great, they're cute and my daughter loves them - which is important at this time. age. They also fit great and wash well (minus shrinkage), but I tumble dry them! Highly recommended - also as a gift ;)
