Wearing a floaty, white Chanel gown, the 29-year-old actress was every bit classic Hollywood glamour, using her look to emulate the '60s with voluminous curls and gold accessories.
It's not the first time Robbie has used fashion to channel Tate, either. During Cannes Film Festival, the Australian actress would often use her wardrobe and beauty looks to emulate Tate, who died in 1969.
Robbie was joined on the red carpet by her co-stars, Brad Pitt and Leonardo DiCaprio, who looked dapper in suits, while other attendees included Britney Spears, who made her red carpet debut with her partner Sam Asghari, Vanessa Hudgens and Stranger Things actor Maya Hawke, Uma Thurman and Ethan Hawke's 21-year-old daughter who also stars in the film.
