Vintage Norton McNaughton L Black Buttonfront Top

Long sleeves, buttonfront with large buttons. I believe this to be vintage. Shoulder pads which are easily removed. No size tag but believed to be a size large. See measurements below. (Length- 21"), (Sleeve Length- 22"), (Shoulders- 17.5" x2 = 35"), (Chest- 20.5" x2 = 41") All measurements are approximate.
