Here is a cool vintage button down long sleeve shirt by Lee. 65% poly and 35% cotton. Handsome brown and white plaid throughout. Seven button front, a button on each cuff (with an extra button on each), button down collar, and a pocket on the left breast. Thin, light weight, soft, and super comfy. 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) 20"
Shoulder to end of sleeve (including cuff) 24"
Length 29"

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