Here is a cool vintage button down long sleeve shirt by Wedgefield. 65% poly and 35% cotton. Handsome plaid of tan and yellow on a gray background. Seven button front, two buttons on each cuff, and a buttoned pocket on the left breast. Paper thin, very sheer, light weight, crazy soft, and super comfy. As close as you can get to not wearing a shirt while still wearing a button down shirt! In great shape with tons of life left! The tag says Medium, but here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 22"
Shoulder to end of sleeve (including cuff) 24"
Length 29"

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