Jenny Packham's gown is modeled on the iconic dress worn by Bond girl Sylvia Trench in the 1962 film Dr. No. Cut from swathes of red silk-chiffon that's softly gathered for movement, it has a one-shoulder neckline topped with a bow and a draped overlay that sweeps across the bodice and cascades down one side. Match your earrings to the sparkly crystals at the waist.
