Cocktail dress LBD NYC high offers end department store

Cocktail dress - "LBD" from the 80's -super CHIC cocktail / mother of the bride dress! The offers straight neckline and slightly fitted silouette are classic and comfortable. There are satin covered buttons on the shoulders, and the LOW cut back has a magnificent swag that reaches to the waist. This is such a stunning look, I love it with a long pearl necklace worn backwards. It has a slit up the back. Looks amazingly sexy with heels. This is a style that will last forever.
It is fully lined, with a zipper in the back. Looks like silk crepe de chine but it is a synthetic blend. Size 10.
Extremely well made. Purchased at a high end department store in New York City.
