This is a cute navy blue suit jacket with thin striped lines, purchased at Marui in Shinjuku. The stitching on the sleeves is also stylish. The size is listed as 0, which I think is equivalent to a size S to M. I usually wear a size M, but this might be better suited for someone with a slimmer build. The length is about 57cm and the width is about 37cm. It's incredibly cute, but there is a small, faint stain on the back. It's not very noticeable, but please be aware of it.
