It's an S size, but it fits like a US size, so it stretches. Please check the size, condition, design, etc. in the photos. By the way, I usually wear M or L, but I chose S because it's large. It has a relaxed fit. I bought it but haven't had a chance to wear it, so I'm selling it while it's still new. It's not a tight-fitting type. It's loose. The design has a slimming silhouette.
