I usually wear a size M in Japanese brands, and this also fit me without any problems. It's OLD NAVY, which isn't available in Japan anymore! :) I'm selling this as I'm decluttering. It has been folded and stored at home, so please be aware of any fold lines. If you have any questions, please ask before purchasing. :) * We will ship it compactly. * Please refrain from purchasing if you are sensitive to items stored at home. * We are not responsible for any postal accidents. * No returns or exchanges. I usually work, so my replies may be delayed, but I will always respond, so please rest assured! Thank you for looking!
