These are denim-style pants I bought from MUJI. They are soft and stretchy denim pants made from a cotton blend. - Size: 90 - Material: 61% cotton, 21% polyester, 11% rayon, 7% polyurethane Thank you for looking. There is a snag in one place (see photo 4), but I've only worn them once, and overall they are clean and still in good condition. They are denim pants with a really nice color.
