This is a super cool vintage long sleeve button down shirt by Benetton. Most likely a poly/cotton blend. Made in Italy. Awesome plaid of browns, black, red, and yellow. Seven button front, button down collar, button on each cuff, and a buttoned pocket on the left breast. The button holes down the front are pretty raggedy, but when it's buttoned up, you can't tell. This has a light flannel feel to it. Very soft, incredibly comfy, and in otherwise great shape with tons of life left! The tag says Extra Large, but here are the measurements. (see pic 5 for how I measure shirts)

Shoulder to end of sleeve (including cuff) 24"
Chest (armpit to armpit) 25"
Length 34"
