I'm selling this because I don't wear it anymore. It's a size S, but it's a bit large, so I think someone who wears a size M could also wear it. I think it would also be good for a clean look as office casual wear ^ ^ It's thick, so you can wear it in spring, autumn, and even winter if you wear Heattech or something similar. Please refrain from price negotiations. <Measurements (laid flat)> Width: Approximately 45 cm Length: Approximately 67 cm
