Here is a super stylish button down long sleeve shirt by Sears in the Jeans Joint line. It is a rich blue with a denim look, but it's much lighter weight. It has awesome red stitching and cool white buttons. Six button front, buttoned pocket on each breast. The button on the right cuff is missing, but it's in otherwise amazing condition. The tag says XL (17- 17 1/2), but here are the measurements. (please refer to last photo to see how I measure men's shirts)

Shoulder to end of sleeve (including cuff) 25"
Chest (armpit to armpit) 25"
Length 31"

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