Here is a handsome and sharp looking long sleeve Western Snap shirt by Montgomery Ward. 65% polyester, 35% cotton. Plaid fabric of blues, red, yellow, and white. Seven button front with two at each cuff, and a buttoned pocket on each breast. Super soft and comfy. Very slightly pilly in spots, but otherwise it's in excellent condition with lots of life left! The tag says Medium 15 - 15 1/2, but here are the measurements. (refer to the last pic above to see how I measure shirts)

Shoulder to end of sleeve (including cuff) 22"
Chest (armpit to armpit) 23"
Length 32
