Classic straight-leg pants. I wore them for an outing. I don't think I've worn them more than five times, but there's some fading around the knees, typical of navy. It's not as noticeable as in the photos. They have an adjustable waist. My child outgrew them quickly, so I hope someone can use them. Purchased at a department store's official store. The size is approximately 150cm, I believe? It's a size 12.
