Muses and musicians gathered at the Hollywood Palladium last night, a very fitting venue for rocker-favorite label Saint Laurent. Hedi Slimane made quite the statement by removing the show from its secure spot in the Paris Fashion Week lineup and moving it to Los Angeles - the day before NYFW kicks off across the country, no less. The fall 2016 collection was pure '70s, filled with glam glitter, luxe furs, and rich velvets. Outfits straight off the Sunset Strip in the glory days of rock'n'roll. No wonder every major name in music from the past few decades were in attendance: Joan Jett, Courtney Love, Lenny Kravitz, Lady Gaga, and even a skateboarding Justin Bieber.
