Size 1 This is a cotton type material. I bought it last fall, wore it about 10 times, and washed it at home after the season ended. As the photos show, there are no noticeable stains, and visually, being a cotton knit, there are no areas with significant pilling or damage. The zipper has some scratches. There is a feeling of wear. I've hung it on a hanger for the photos, but I usually store it folded. If you have any concerns, please comment and I will upload close-up images. It's size 1, but it's also stretchy, so I think anyone can wear it. I am 178cm tall and of a slender build, and I wore it.
