I'm leaving it in the pocket as it is a good piece of history. There is no visible size or tag, please refer to measurements for best indication of fit. Shoulder to shoulder - 16.
Pit to pit - 18. Collar to waist - 20.Shoulder to cuff - 21. Pit to cuff - 16.
My best guess is that this would most likely be for a larger child (perhaps a young teen) or a smaller adult. My neighbor is 4'11 and 80lbs and this is just a bit too big for her in the shoulders/sleeve length. Note: Listed in men's category as a small, but it may be woman's or child's size. No tag on item, see measurements for sizing.Of course given the age (likely 60-70 years old) there is some signs of previous wear but I did not find any rips in the leather. The primary areas of wear are the collar, shoulders, and elbows. The chrome buckle and other chrome pieces are slightly tarnished (may polish out). The inner lining is slightly worn, with some small holes and a few loose threads but overall its not too bad considering the age.
To me, it has a beautiful vintage patina, and I wouldn't change a thing, but I mention these characteristics in the interest of full disclosure.
