This tag is very rare! Brooks Brothers sport shirt Also, made in USA USA shirts tend to be large, so I think the M size is a golden size. There is fraying under the collar, please check the photos. I think it's from the 80s-90s, but please judge for yourself by the tag. Furthermore, it's a super nice check pattern. Since it's large, I put it in the L category. Please be sure to refer to the actual measurements. Mr. Tsuneta's photos are for reference.
