This has to be one of the best celebrity wedding dresses we've ever seen.
Nicky Hilton looked gorgeous in a lacy, long-sleeved Valentino Couture wedding gown on Friday, as she stepped out of her London hotel headed to marry banking heir James Rothschild at Kensington Palace.
Check out the 31-year-old socialite's amazing train.
Nicky had quite the hand in designing the gown as well. "Ever since I was a little girl I wanted Valentino to design my wedding dress. Valentino is the definition of timeless elegance, I don't think there's another couture house like it," she told Harper's Bazaar.
"I went through every look from their collections over the last 10 years," she added. "I studied the archives, and I just sent notes about details I liked -- a certain sleeve, a high neckline."
And the result -- six months later! -- is absolutely stunning: a custom couture gown with guipure lace, crystal embellishments, a balloon skirt and a nearly 10-foot train. The bride completed her look with a pair of white Christian Louboutins, inscribed with "Mrs. Rothschild."
