The left one is size 105, and the other two are size 120. Only the middle one is unused. They run small. My slender second daughter said they were tight, so she only wore them a few times. My second daughter is slender, but her legs are muscular, so I think they would be easy to wear for children with thinner legs. The two that were worn have some pilling, but there are no tears, so would anyone be interested if they don't mind?
