I bought this because it's cute, but I haven't had many chances to wear it, so I'm selling it at a low price. The sleeves have cute buttons that match the button on the back. There's a slit under the back button, which is cute (see photo 3). It's also lined, so it's not see-through. The size is M, but the waist is elastic and has a ribbon you can tie, so it fit me perfectly, and I usually wear a size L. When I wear it (I'm 163cm tall), the length is just to my ankles.
