Alex Perry EXCLUSIVE AT NET-A-PORTER. Alex Perry's 'Laura' gown will never date, even when you look back at the pictures from your big day in years to come. Cut from sculpting white satin-crepe, it's fitted with internal boning for support and has an elegant strapless sweetheart neckline that flatteringly frames the decolletage. It's gathered through the bodice and hugs the hips before gently kicking out to an elegant train - guests will catch a glimpse as you make your way down the aisle.
