Saw a dude on Parks and Recreation wearing an RRL flannel from the Shipyard collection tonight. Can someone give me the arm sleeve opening (from shoulder seam to the armpit) on a large RRL shirt please? My chest measures 40" and most of my best fitting shirts measure 21" p2p. I saw it was said that I would be a large in RRL (where it seems the p2p ranges from 22" to 23" so I'm trying to see how high the armholes are. Thanks.
