Here is a handsome and sharp looking long sleeve Western Snap shirt by Wrangler. Most likely a poly/cotton blend. The pattern is a plaid of blue, black, maroon, and tan. Six snap front with one button at collar. Two buttons on each cuff, and a buttoned pocket on each breast. This shirt is in amazing condition with lots of life left! Here are the measurements.

Chest (armpit to armpit) 21"
Length 33"
