Here is a cool vintage long sleeve Western snap shirt by Wrangler. Feels like a poly/cotton blend. Great plaid design in vivid blues, white, green, and maroon. Seven button front, three buttons at each cuff, buttoned pocket on each breast. In excellent shape with lots of life left! The tag says Large, but here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 23"
Shoulder to end of sleeve (including cuff) 24"
Length 32"

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