Bringing a touch of French fashion to the California coast, Balmain creative director Olivier Rousteing celebrated the store's first Los Angeles outpost in Melrose Place with his closest celebrity friends.

The evening also celebrated the launch of the Balmain X Beats by Dre headphone collaboration, fronted by another Rousteing BFF, Kylie Jenner, and saw a Beverly Hills mansion transformed into a Balmain-style club complete with pink strobe lights, indoor pool and fashion show on the staircase.
Completing the impeccably dressed crowd were industry stylists, influencers like Aimee Song, and rapper group Migos - who even treated the crowd to an impromptu performance in the mansion's sprawling gardens.
Ain't no party like a Balmain party.
