This is Uniqlo loungewear. The elastic in the waist has stretched out and no longer fits my body shape, so I'm selling it because I haven't worn it recently. (It can be adjusted with the drawstring, but the elastic is quite stretched. I usually wear a size S, and the waist is quite loose on me, so I'm listing it as a size M.) It has pockets and is made of terry cloth, which made it useful as loungewear. There is some wear and tear. Also, there is a small hole in one part of the front (I've included a photo). Please purchase only if you understand all of the above.
