Alexandre Vauthier re-imagined the lavish surrealist ball held by Marie-Hélène de Rothschild in 1972 for his Spring '20 couture collection. Worn on the runway, this stretch-jersey gown is saturated with crystals that sparkle as it skims over your curves and falls to a swishy asymmetric hem. Highlight the halterneck with a sleek chignon, just like actress Tina Kunakey.
