Here is a super handsome short sleeve button down shirt by Sears Thumbs Up. Tan background with a hint of salmon in it, criss crossed by striping in maroon, black, and yellow. 65% poly, 35% cotton. Seven button front, with a buttoned pocket on each breast. In excellent shape with tons of life left. The tag says Small, but here are the exact measurements. (Please see the last picture to see how we measure shirts)

PS I had to take pics of this shirt on my female dress form, as it was too small to fit on the male one. That's why it looks pretty large on the mannequin.

Chest (armpit to armpit) 18"
Shoulder to end of sleeve (including cuff) 9"
Length 31"
