Valentino Garavani officially opened the exhibit honoring his life and more than five decades in fashion, “Valentino: Master of Couture” at the Somerset House in London! The party matched the Italian designer’s level of fabulousness, with stars like Victoria Beckham (in her own design), Sarah, Duchess of York, and Princess Beatrice all in attendance. The exhibit displays Valentino’s most iconic couture pieces, including over 130 hand-crafted designs worn by style icons such as Jackie Kennedy Onassis, Grace Kelly, and InStyle cover girl Gwyneth Paltrow. It runs through March 3, 2013; visit somersethouse.org.uk for more information. Click through the gallery to see more fantastic fêtes!
