Black and gold woven sweater

Black and gold woven sweater. Good used condition. Some spots where the gold “thread” is coming out but it’s not ever completely unwoven. Widely woven so I would wear something underneath. Not labeled for size but I would assume it’s a medium. Has some stretch. Measurements when flat (unstretched): Pit to pit - 21.5 in Collar to sleeve hem - 27.5 in Hem - 16.5 in (can stretch wider) Shoulder to hem - 25 in
