Heidi Klum Shares All The Details About Her Fairytale Wedding Dress

First, Heidi Klum and her new husband Tom Kaulitz got married in a private legal ceremony, far away from public way. Then, six months later this August, the couple went all out with a much more lavish, star-studded second wedding aboard a luxury yacht near the island of Capri in Italy. For that elegant celebration, Klum wore a gorgeous, off-the-shoulder gown that was perfect for the event's nautical vibes. In a new Instagram video, the model and former Project Runway star finally revealed all the details about the dress—including who the secret designer was.

It turns out that the gown was made—drum roll, please—by none other than Valentino. Klum shared how her look was put together in a behind-the-scenes video that she posted to Instagram this week, showing her being fitted into the stunning creation by Valentino's creative director Pierpaolo Piccioli.

Piccioli explains in the clip that the inspiration for the couture piece was “romanticism and lightness” and that “the setting was fitting for her and for her personality.”

Meanwhile, the video has tons of footage of Klum looking absolutely thrilled. She dances around in the wedding dress and skips from one corner of the room to another, cheerily shouting, "It moves!" Klum paired the gown with a gauzy, full-length veil for a classic bridal touch.

Klum had published a shot from the wedding earlier this month, giving fans a glimpse into how extravagant the big day was. The yacht on which the couple got married was the Christina O, the same place where Jacqueline Kennedy and Aristotle Onassis hosted their own wedding in 1968. Klum and Kaulitz had the Christina O completely draped in white and pink flowers as they tied the knot, and the decor brought out certain elements of Klum's gown, which featured a full ball skirt covered in floral appliqués. "We did it!" Klum wrote happily in the caption. "Mr. & Mrs. Kaulitz."
