This is a long-sleeved vintage flannel shirt by POLO by Ralph Lauren. It has a tight silhouette and looks really cool. It's size S, but because it's a US size, it's about a Japanese M to L. If you buy it at a used clothing store, it would easily cost over 20,000 yen. It has a classic black and white check pattern, making it easy to match with any style. The fabric is thick and perfect for fall, winter, and even early spring. It has chest pockets on both sides, combining practicality and design. The size is "36", which is equivalent to a size S. ● Brand: POLO by Ralph Lauren ● Color: Black x White (Check Pattern) ● Size: 36 (Equivalent to S size) ● Material: Cotton (estimated) ● Country of Manufacture: Made in the Philippines ● Condition: There are no noticeable stains or scratches, and it can still be used.
