EXCLUSIVE AT NET-A-PORTER. Roksanda's 'Adyn' gown is the kind you'll still love when you see it in photos from your wedding day years from now. It's been crafted in England from smooth silk-crepe and trimmed with delicate tulle along the neckline and waist. Cut for a slim fit through the bodice, it nips in at the waist and falls fluidly to a floor-sweeping hem. Wear it with strappy sandals.
