From Sarah Jessica Parker and Julianne Moore to Kim Kardashian's other half and Gossip Girl's Chace Crawford, the stars came out for the launch of the just-released Maison Martin Margiela for H&M line.

Each H&M collaboration celebration tops the previous, from Marni's luxe Moroccan-inspired soiree to Versace's $10 million dollar extravaganza.

A 9-story building of fashion-meets-art performances, topped off with a light show and confetti rainstorm, the Maison Martin Margiela x H &M event was just as elaborate, tapping into Belgian designer Martin Margiela's artistic avantgarde aesthetic.

Along with a list of Hollywood A-listers, the party brought plenty of fashion industry insiders, from Alexander Wang to Doutzen Kroes.
