Abercrombie & Fitch It's a US size S, but I think it's about a Japanese size M. As you can see in the photos. I bought it for overseas travel and only wore it for about 10 days in total. It's in good condition. It makes you look stylish when you wear it, I recommend it. I've included a photo of me wearing it at the end. I'm 163cm tall, I hope this helps you.
