EXCLUSIVE AT NET-A-PORTER.COM. Zimmermann's maxi dress is everything you'd expect from the label – relaxed and romantic with a decidedly bohemian spirit. Cut from swathes of billowy ivory silk-georgette, it's decorated with Swiss-dots and tiers of guipure lace. The elegant off-the-shoulder neckline is kept in place by halterneck ties. We think it's the perfect choice for a beach wedding.
