Thank you for viewing! This is a top with a flared sleeve design made of yellow lace fabric. The size is listed as S, but it runs large, so I think even those who usually wear M can wear it without a problem. I am of average build and usually wear size M, but it fit perfectly even when I wore a long-sleeved T-shirt underneath. I don't see any stains or dirt.
