I wasn't sure about the size notation, but the size felt just right for me, who usually wears M to L size. I tried it on after purchasing, but it was different from what I expected, so I'm selling it. Purple cropped length sweatshirt with a half-zip design and embroidered logo. It's fleece-lined, so it's warm even on cold days. Thank you for viewing. Color...Purple系 (Purple-based) Stains, tears, odors, etc...None
