Y-3 track pants. They have white lines running diagonally down the sides, which makes the silhouette look beautiful. The size is S, but it's equivalent to a general M size. The fit is a relaxed, oversized style, but the cuffs are fitted, creating a beautiful silhouette! These are high-quality track pants, typical of Y-3. I purchased them on Mercari and wore them about 5 times. There are no noticeable scratches or stains.
