I got a set for her 4 years ago and she loves them so much especially the pink ones so we ordered them again. (She wore holes in her old pink pair because she was playing outside with no shoes, just pink socks. ๐ฅด). They have enough stretch to fit your leg perfectly and just below the knee. She is slightly below average size.
