For the evening festivities, Giorgio Armani Privé once again swathed the bride in white embellished with crystals and stones, this time off-white silk chiffon with Swarovski crystals and gold and platinum-colored stones. The dress featured a transparent upper portion and a four-tiered skirt. Oh yeah, and Albert also had a wardrobe change.
She also wore a new jewel in her hair, this one a gift from Albert (one of two she received, the other one you can see here and which is the Ocean convertible necklace and tiara from Van Cleef & Arpels). This piece is called the Diamond Foam Tiara, and you can read more about it here.
UPDATE: Here is Armani's sketch for the evening gown
