h.i.p. cardigan/vest from the buckle

h.i.p. cardigan/vest from the buckle for some weird reason, there is not a size included on the tag but I would put this somewhere between a medium and a large. Please be sure to check out all photos, I just noticed a pinhole at the bottom of the shirt/vest. to armpit is about 17 inches and up and down is about 25 inches.
