Black and off white strapless cocktail dress size 12 NWOT

NWOT off white and black cocktail dress. Perfect wedding guest dress. Strapless and satin top - with horizontal pleats throughout. Black part meets the bottom part at natural waist. The bottom is taffeta (?) and lined with a little tulle. The best part is the gorgeous three dimensional flowers along the bottoms. Kind of a swirly ruffle pattern. I bought it Dillards and the brand is Max and Cleo
