Excellent condition. Looks like it was bought then stored for many years. A crease on the back (pictured) and a small on the front which could be pressed out. Please see photos and ask any questions!
I usually wear a men's small, sometimes medium. This fits me well (see photos). Keep in mind it'll be over other, thicker clothing typically.
Measurements:
Length down back: 22 1/2"
Length across shoulder seams: 12 1/4"
Width at first button (chest, laid flat): 20 1/2"
Enjoy!
