This gown is all about artful engineering. The pleated Empire bodice is molded like a real bra and the hand-beaded Swarovski crystal circles are a new look in bridal embroidery. Yards of silk-chiffon produce one fabulously fluid skirt. About $4,300, Jenny Packham. Earrings, necklace and ring, Tiffany & Co, 800-526-0649. Shoes, Stuart Weitzman.
