Stewart's '50s-inspired style was the handiwork of hairstylist, Adir Abergel, who created a super high ponytail at the crown of her head and rolled the front section of her hair into what was called "bumper fringe" in the 1950s.
"I loved creating this moment for this year's Met Gala with the theme: "IN AMERICA: A LEXICON OF FASHION." Kristen in my muse forever!" Abergel wrote in a caption accompanying a photo of the vintage look. Stewart's new hair colour was also dreamed up by Abergel, who collaborated on the new blonde tone with LA-based colourist Daniel Moon for the actor's appearance at the Venice Film Festival two weeks ago.
