Here is a hip and cool long sleeve button down shirt by Levi's. Most likely a poly/cotton blend. Great plaid of blue, gray, tan, white, and red. Supposed to be a six button front, but the top button at the collar is missing. One button on each cuff, buttoned pocket on the left breast. Thin, light weight, and super soft. This one is in amazing condition with tons of life left! Here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 21"
Shoulder to end of sleeve (including cuff) 24"
Length 30"

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