Amour Vert Black Sweatshirt Mens Small or Women's Medium

This cozy, organic cotton sweatshirt is in EUC. It was listed as a Men's Small, which I got for a male family member but I ended up wearing it as a Women's Medium. I'm downsizing my sweatshirt collection. I took a photo of the collar to indicate slight fading at the ribbing for total transparency, but it's not noticeable unless you're looking for it.
