Thank you for viewing. Instant purchase is welcome. Since it's already priced low, please refrain from bargaining. ★ We offer discounts for multiple purchases, so please comment. GU Size S It's a very loose fit, so It seems like it would fit a size M as well. It's a gauze-like, see-through material, making it feel cool. Also recommended as a light jacket. I think you can use it without any noticeable stains. Please check the condition and size in the images. This is a used item, and I am a private seller. We will ship with simple packaging, so please purchase only if you understand. If you have any questions, please ask ^o^
