Full of dozens of colorful kaleidoscopic costumes, Barbie boasted an impressive wardrobe for its entire cast. Even background characters wore memorable garments, from President Barbie to Doctor Barbie. With decades of inspiration from the dolls, the film showcased clothes from different decades of Barbie history, like Margot Robbie's stereotypical Barbie wearing the exact same black and white striped swimsuit that the first ever Barbie doll donned back in the 1950s. Thanks to costume designer Jacqueline Durran, everyone's favorite doll got to wear many dazzling outfits.
