These Korean leggings were worn frequently for both daycare and outings. They are size 90 (7). My son, who is now a size 100-110, can no longer wear them, so I'm selling them. I bought the same ones in a larger size. They are easy to wear and are recommended for everyday use. They are Korean leggings, so there may be some fraying, but they haven't worn out much despite being worn quite a bit. If you don't mind, they can still be worn a lot. Easy-to-match colors: 2 black and 1 ivory, a set of 3. Highly recommended! Please consider them!
