Purchased from ZOZOTOWN. I wore them twice, but they no longer fit, so I've been storing them at home. I checked for any stains, but there aren't any! ^_^ The inside is also in very clean condition. They are in excellent condition with no noticeable signs of wear or fading. They have a good amount of stretch ◎ The waist also stretches ◎ The color is dark navy. Instant purchase is okay!
