I bought this a few years ago and wore it often, but there are no noticeable stains or damage. The fabric is also sturdy. I couldn't find the size listed. The body width is approximately 43 cm and the length is approximately 53 cm, so I've listed it as M. The fabric is not too thin and is not see-through. As you can see in the photos, it's wider at the bottom, so it's flowy and has room around the stomach.
