Classic fit long-sleeved striped design shirt, made by Ralph Lauren. - Brand: Ralph Lauren - Fit: Classic Fit - Color: Striped (blue and white) - Sleeve Length: Long Sleeve - Size: 8 I think it's about a small M size. I bought it used on Mercari. I've worn it about 3 times. It's hard to see in the photos, but there are two yellow stains on the front of the left sleeve and one yellow stain on the left side of the collar. It's easier to see with the naked eye, so please refrain from purchasing if you are concerned. There is also some yellowing of the collar.
