Margot, who plays Sharon Tate in the film, stunned in a flowing white dress paired with a gold chain purse.

The upcoming film visits 1969 Los Angeles, where everything is changing, as TV star Rick Dalton and his longtime stunt double Cliff Booth make their way around an industry they hardly recognize anymore.

Once Upon a Time in Hollywood hits theaters on July 26th.

FYI: Margot is wearing Chanel. Guests at the premiere enjoyed specialty Casamigos cocktails and shots in boot shaped shot glasses.
