Thank you for viewing. It's made of a thick, ponte-like fabric. It's a size S (36), but it has a relaxed fit, and I think it can be worn by those who usually wear a size M. I've worn it a few times, but there are no noticeable stains. Please refrain from purchasing if you are concerned, as this is a personal inspection and it has been stored at home. - Brand: OPAQUE.CLIP - Product Name: Skipper Blouse - Style: Can be set up - Color: Light Gray, Ivory, Greige Office
