Stunning blouse with deep plunge back

Stunning blouse with deep plunge back. Black sheer fabric with silver and blue sparkles all over and in impeccable condition! Padded shoulders give it a very cinched waist! One single fabric-covered button in the back! Pair with a black pencil skirt for a very sexy retro look! Purchased at vintage shop but sadly never wore and now it does not fit! 😔 13” waist side to side 17” bust pit to pit
