I purchased this last year. It's Airism, so it has a smooth fabric and a comfortable feel. It has stretch. Also, the ankles have a fitted design. I haven't used it much, and I don't think there are any stains or damage. The waist is elastic and adjustable with a button. The color is difficult to see due to the lighting, but it's navy. Please refer to the image from the official website in the first photo. - Color: Navy - Style: Active Pants - Material: Stretch material - Design: Elastic waist Thank you for looking.
