Uniqlo Tapered Pants Gray Glen Check Pattern Size S The waist is elastic. Purchased at Uniqlo several years ago and worn a few times, then stored. There are no noticeable stains, but the thread inside one of the fake pockets on the back has come loose. It's not noticeable at a glance, so there shouldn't be any problem, but please refrain from purchasing if you are concerned. Thank you.
