Vintage Long Sleeve Flannel Blouse by Off-Shoot

Here is a super cool vintage blouse from the 70s/80s by Off-Shoot. 100% cotton. Plaid design of reds, green, yellow, and white. Seven button front with button on each cuff. Sort of on the thinner side for flannel, light weight, slightly sheer, soft and comfy. It's in excellent condition with tons of life left. The tag says Size 11, but here are the measurements taken laying flat. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 20"

Sleeve 22"

Length 24"
