The 16-year-old star made the sartorial shout-out to her Maleficent character as she greeted fans. Fanning, who paired the colorful dress with silver heels with red straps, is in Japan for the film's Tokyo premiere.
This isn't the first time the teen has honored Sleeping Beauty with her style. In May, she wore Charlotte Olympia's Sleeping Beauty heels to a Paris photocall for the Disney film co-starring Angelina Jolie. Jolie, meanwhile, has been wearing custom Christian Louboutin horned heels inspired by her own character.
So, um, is anyone else itching to hit up the Disney Store today?
