I purchased this at the KEYTALK SHOP, which was held in Shimokitazawa for a limited time a few years ago. It's one size, but it's quite large, about the size of a men's L. I've only worn it twice as casual wear, so there's no pilling, but there is a slight stain as shown in the second photo (less than 1cm). Please consider purchasing after understanding the above. m(_ _)m Yuki Yagi
