Nicky Hilton wore a $70,000 Valentino custom gown for her wedding to billionaire James Rothschild at Kensington Palace's The Orangery.
The hotel heiress looked stunning in the bridal dress, which designers Maria Grazia Chiuri and Pierpaolo Piccioli made from "precious vintage lace," "three different tones of ivory" and "richly embellished with crystals".
They wrote: "[The gown] was composed with three different tones of ivory and silver guipure richly embellished with crystals. The high neck bodice stitched to a precious balloon skirt ending with a three meter long train. Covered with a long veil is enriched all around the edge with a precious vintage lace."
She previously said: "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."
