Here is a classic vintage long sleeve button down flannel shirt by Sears. 100% acrylic. Great plaid pattern of brown, tan, camel, and maroon. Seven button front, one on each cuff. Buttoned pocket on each breast. Warm, soft, and comfy. There is a very small hole on the left sleeve (see pic 4), and a tear in the lining inside the neck (see pic 5). The former is really hard to see, the latter is invisible once it's on. This one is in otherwise excellent shape with tons of life left. The tag says XL, but here are the measurements. (refer to the last pic above to see how I measure shirts)

Shoulder to end of sleeve (including cuff) 26"
Chest (armpit to armpit) 25"
Length 32"

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