Most recently, the actress graced the red carpet at the 2024 Golden Globes wearing a hot pink custom Armani gown, which was inspired by the 1977 Superstar Barbie doll.
Since the beginning of the movie's press tour, stylist Andrew Mukamal has worked with labels including Prada, Vivienne Westwood, Bottega Veneta, Balmain, Versace, Valentino and Schiaparelli to keep Robbie in character on the red carpet.
"We're finding Barbie references from decades past and just doing it really for the big Barbie fans out there, people who are actually collecting those Barbies," Robbie told People at the July world premiere of the film in Los Angeles. "We're hoping to get them excited. We're pairing Barbie references with great designers."
Next up is the Oscars and fans hope Robbie's Barbie-style streak will end with a pink exclamation point.
"Barbie" earned a total of eight Oscar nominations this year, including best picture and best supporting actress for America Ferrera.
