It's a warm, velour-like material. It's a purple shade. I was using it as loungewear. It's been home-cleaned and stored. The tag has deteriorated from washing. It's a size S, but the waist is elastic, so I usually wear a size M, and it fits. I'm selling it because I bought similar pajamas. I will compress it as much as possible for shipping. Thank you for your understanding. Inseam: 62cm Pattern: Solid Uniqlo Loungewear Velour Uniqlo Velour Pants
