Vintage lace sweater/jacket/button down blouse, size S-M

Black 100% nylon Button down Scalloped hem See through…looks beautiful over a cami! Could be described as a dressier lightweight laced sweater or buttoned down blouse! Only worn a few times Tag says L, but I’d say it would fit small / medium, definitely not large No rips or stains, only flaw I see is tag has some yellowing (vintage!)
