This is a stand collar overshirt from RIM.ARK! I was interested in it because Kandama-san wore it, and I bought it online! (Product number: 460ESS30-0220) I've worn it a few times! I think it's in good condition and a beautiful item! Please consider it! (*˘︶˘*).｡*♡ I'll include the product description below. The oversized shirt with a high neck creates a mannish atmosphere, and the design cuffs and panel lines on the sleeves are subtle details. The fabric has a wool-like appearance, but it's actually a wool-like synthetic fiber that's wrinkle-resistant and has a smooth texture, making it very comfortable to wear. It looks great as an outer layer and can be worn throughout the year. Color... Black
