I bought this for around 10,000 yen a few years ago. I've worn it a few times, but I think it's in pretty good condition. There was no size label, but it fit me fine, and I usually wear a size M. It's more like a three-quarter sleeve length rather than long sleeves, and the fabric is firm and has a luxurious feel. (Please refer to the model's photos) It doesn't wrinkle and isn't see-through, so I think it's easy to wear.
