Here is a cool long sleeve button down shirt by JC Penney. It's a handsome looking brown, black, and white plaid pattern. Two pockets on the front. It's 65% polyester and 35% cotton. Please note that at some point, the very bottom button was re-attached. For whatever reason, the surgeon used white thread to sew it back on instead of black like all the others. Not the end of the world though. The tag says large 16-16 1/2, 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 31"
