These skinny jeans are quite tight, but the stretch makes them easy to move in. I'm selling them because the waist has become too loose. I've worn them about 5 times since I bought them new, but only for short outings, so I don't think there are any noticeable scuffs or stains. I think they can be worn year-round except for summer. The waist is labeled as 31 (78.5), but it stretches. I'm not sure if they're a good fit for a size M. The color is like this from when I bought them. Please consider purchasing if you are satisfied with a used item.
