I'm selling this because my tastes have changed. The tag was not attached when I purchased it, so I don't know the material or size, but I usually wear a size M, so I think it's a size M. It feels good against the skin. It's stretchy. There are no noticeable scratches, stains, tears, frays, fading, or pilling. Please refer to photos 2-4 for the size. There are no smokers or pets in my home. I wore it with care, but it is used clothing, so please understand this before purchasing. Returns, exchanges, and complaints are not accepted, so please understand.
