St. John's Bay thick flannel shirt, and it's a blue and black block check. The tag is old, probably from the 80s or 90s. Only one button on the sleeve. Similar ones are selling for the high 8000 yen range for L size, and even a damaged XL is around 8000 yen, so I think this is a good deal. The length isn't too long, so it's probably in style right now. It's not a Big Mac. I don't think there are any major problems.
