Ralph Lauren rugby shirt, navy & white, 100% cotton. Brand: Polo by Ralph Lauren Color: Navy & White Material: 100% Cotton Size: M Flat measurements: Length: 75.5cm Shoulder width: 52cm Width: 60cm Sleeve length: 68cm Please understand that there may be some errors due to amateur measurements. Although it is marked as size M, it has a more relaxed fit than a Japanese XL. It really feels like it's made in America. I wore it quite often, so you may feel some yellowing of the white areas due to aging. Also, I found various small stains during the listing check (please check images 5-8). I washed it, but they didn't come out, so I will list it as is. Since it's a rugby shirt, if you can appreciate the above stains as part of the vintage feel, please consider purchasing it.
