These are wide pants made of soft fabric! They have a comfortable elastic waistband. There's no size label, but the waist is elastic, so they should definitely fit up to a size M! The length is just above the ankle on me, and I'm 155cm tall. The color looks gray, but it's more of a beige-ish color, I think. If you'd like me to confirm the color, please leave a comment. There's a small stain, as shown in the fifth photo. Please leave a comment if you have any questions. Please be aware of any folding wrinkles.
