With all due respect to Mr. de la Renta, he didn't invent the cocktail dress. Neither did Victor Costa, but he was the first to re-invent it for a new generation in the 80s, when the 50s hourglass silhouette was resurging in a big way. This dress is dramatic yet simple somehow, with a fitted bodice and ruffled skirt. Silk dupioni. By Victor Costa. Zips up the back. Measures 34" bust, 26" waist, 42" long.
