I am selling this item because I no longer wear it. The material is cotton, so I think it feels good against the skin. There is no size label, so I'm not sure, but based on how it fits, I think it's around a size M. The length and width are approximate measurements taken by a layman, so please understand. I don't see any noticeable stains, but please refrain from purchasing if you are concerned about minor details, including any oversight. Thank you.
