Thank you for viewing. I purchased this new with tags on Mercari and wore it once. I home-cleaned it with Emal. I am selling it because it no longer fits. It's a boat neck. I cut off the tag that was attached to the inside, as I believe it was large. The product description at the time of purchase stated that it was a size S, but it seems to be equivalent to a size M. The fourth image is a picture from when I purchased it.
