Princess Diana rarely changed her hair, preferring to stick with the styles that she knew and loved. It's an essential part of the "Diana look", and the team understood that nailing this part was key. To get the styles, Stewart wore wigs all throughout the film to re-create Princess Diana's iconic hairstyles, including the shaggy cut that's synonymous with some of Diana's biggest fashion moments in the 1980s. These were handmade by Samuel James and styled by the film's makeup and hair designer, Wakana Yoshihara.
