While Alexander Wang is known for having some of the craziest after-parties during NYFW, in Paris it's Balmain's Olivier Rousteing who throws down the most buzzed about bashes during PFW. Last season he celebrated with Rihanna, Jessica Alba and Ellen von Unwerth at famed cabaret Le Crazy Horse and this year the after-party took place in a Rococo fever dream of a private residence and got everyone from Kim and Kanye to Kendall Jenner and Karlie Kloss to come out and raise a glass of champagne. Take a peek at photos from the night, below.
