Here is a hip and cool long sleeve button down shirt by JC Penney. It's 65% polyester and 35% cotton. It's a great plaid of brown, white, rust, green, and gray. Great looking with lots of life left! The tag says XL 17-17 1/2, but here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 24"
Shoulder to end of sleeve (including cuff) 24"
Length 32"

This item is sold from a vintage boutique in Roanoke, VA.
