This is something I bought at an outlet. They're pants with an elastic waistband. - Color: Blue系 (Blue-toned) - Design: Elastic waistband, with drawstring - Pockets: Back pocket included - Style: Casual The fabric is easy to move in, so you can wear them in any situation. I wore them often in the summer, and they don't seem to have any stains, but I apologize if I missed anything. They're the perfect length even for me, at 177cm!
