Thank you for visiting. Although it is an S size, it seems that a person who wears an M size can also wear it. I wore it about 3 times and kept it in the closet. I have home-cleaned it. There are no noticeable stains, but please understand that this is from an amateur's perspective. Please refrain from purchasing if you are looking for perfection or are sensitive. Color... Beige Material... Acrylic Neck... Crew neck/U-neck Season... Autumn/Winter Stains, tears, odors, etc.... None
