I bought this at a clothing store in Shin-Okubo, but I haven't had a chance to wear it, so I'm selling it (⋆ᴗ͈ˬᴗ͈)” It's new, without tags. The size is definitely suitable for those who usually wear S. I usually wear M, but I could wear it when I tried it on! The fabric doesn't stretch, and there's a zipper on the right side under the arm. I'm using the snidel tag for reference! Color: White Material: Polyester (synthetic fiber) Season: Spring/Summer
