I don't see any stains or dirt. It's not stiff denim, but a stretchy material, so I think it's easy to wear. Striped side denim pants, size 90. The buttons and zipper are decorative and don't actually open or close; they can be worn like leggings. - Color: Denim Blue - Size: 90 - Suitable weight: 13kg - Design: Striped side Thank you for looking.
