Kim Kardashian and Ye (Kanye West): $12 million

Few weddings have generated the cultural gravity of Kim Kardashian and Kanye West’s multi-country avant-garde spectacle on May 24, 2014. The couple turned their wedding into an international odyssey, flying their entire wedding party from a lavish pre-wedding brunch at the Palace of Versailles in France straight to Italy via private aviation. The ceremony itself was held at the historic Forte di Belvedere in Florence, where the couple exchanged vows in front of a towering, 20-foot-tall solid wall of white gardenias and peonies. The bride wore an immaculate, $500,000 long-sleeved Givenchy Haute Couture gown designed by Riccardo Tisci. Every detail was meticulously curated by West, including a massive, singular marble dining table engraved with the names of their guests and a live performance by Italian tenor Andrea Bocelli.
