Vintage Amati by Barclay Polo Shirt Mens Large Blue Knit Rockabilly 70's Striped. Has a bit of stretch to it, but fits very tight for a modern large. Unless you're going for a very classic slim fit, I would say this fits more like a modern medium. See measurements for sizing. In good pre owned condition, has some light wear, a few little snags, no major visible flaws. See photos for full details. Measurements included in the photos. Message me with any questions, thanks!
