Why Barbie Trades Chanel For Birkenstock, According to the Movie's Costume Designer

When Stereotypical Barbie realizes that her feet have turned flat, she struggles to walk in heels on her trip up to Weird Barbie's house. "I'd never wear these shoes if my feet were shaped like this," she says as she climbs up the stairs, where she's presented with an original flat Birkenstock representative of the "real world." As the film progresses, the Birkenstock continues to symbolize the "ugly" antidote to the Barbie-foot heel.
