Thank you for viewing. I received this a long time ago and have kept it in storage without using it. It's an old design, but I think it looks really cool when worn now. It's a rare item to find. It's a top and bottom set, so you can use them together. The size is indicated as O, but I think it's about L. The zipper opens and closes without any problems. Please consider purchasing if you understand that this is a used item. I will pack it compactly for shipping. Thank you for your understanding. Yomiuri Club
