This was worn by my daughter, but she didn't wear it many times, so there's no blackening on the seat or knees, etc. m(__)m The waist is elastic and stretchy, and it seemed easy to wear, but I'm selling it because I have a lot of them! It's size 120, but I feel it would fit children around size 110-115. For reference, the inseam is 47cm! Stretch pants, trousers, long pants, boys, girls, kids, unisex, full length, 10-part pants C
