These are Uniqlo pants. I've worn them about three times. There are no noticeable stains or anything of concern, but please understand that these are used items before purchasing. The color is brighter than in the photos. I think the closest color is light blue. Please note that the material wrinkles easily. The material is smooth and silky. They are about 8-分丈 (eight-tenths length). For reference, I am 160cm tall. I usually buy size M, but these were a perfect fit in size S. If you have any questions, please feel free to comment (⋆ᴗ͈ˬᴗ͈⋆) Please read my profile before purchasing. Thank you for your cooperation.
