His death was tragic, and happened much too soon, but in the 15 months since Alexander McQueen’s untimely passing, his eponymous fashion label has thrived. From a successful runway presentation by his successor, Sarah Burton, to the label’s biggest moment yet — designing Kate Middleton’s wedding dress — it’s been a big year for the British brand. Tonight, scores of stars will descend upon New York City’s Metropolitan Museum of Art to celebrate the house of McQueen and the museum’s latest exhibit, “Alexander McQueen: Savage Beauty,” at the annual Costume Institute Gala, chaired by Salma Hayek and husband François-Henri Pinault. Then on Wednesday, the installation will officially open to the public, offering more than 100 stunning examples of McQueen’s work, from his first post-graduate collection to his final runway presentation, seen on the catwalk in February 2010. The exhibition is on display at the Met through July 31, 2011; stay tuned to PEOPLE StyleWatch tonight for all the latest from the big event.
