Sandpiper Vintage Denim Vest Unisex Blue 70s Funk

Sandpiper Vintage Denim Vest Unisex Blue 70s Funk I was under the impression this was a women's vest until I did a little research and it seems like it might be a men's instead. If so, it's on the small side. If it's a women's, then it's on the bigger side. Please see measurements. No size tag or fabric content tag. Quite stiff. Snaps down the front. Little bit of a rough spot under the left arm as shown. Overall great shape especially considering its age.
