In what may be the most Barbie thing we've ever heard, Margot Robbie enforced a weekly pink day on the Barbie set. According to her co-star Ryan Gosling, who plays Ken, the lead actor brought in a dress code for all of the cast and crew.
"Margot had this pink day once a week, where everyone had to wear something pink. And if you didn't, you were fined," Gosling told People. "She would go around collecting the fines, and she would donate it to a charity. What was really special was just how excited the male crew members were. At the end of the film, they all got together and, with their own money, made pink crew shirts with rainbow fringe.”
