On Sunday, the 37-year-old actress and director revealed that she would be celebrating the spooky holiday by dressing up as Dolly Parton — large prosthetic breasts and all. First sharing a photograph of herself in costume on her Instagram Story, Wilde posted an ant's eye view of her tribute attire, which was composed of a large blonde wig, blue makeup over her eyes and multi-colored top tied to cover her fake chest. "I ❤️ you @dollyparton," she wrote alongside the pic. In another post, Wilde shared a behind-the-scenes video of herself bouncing around with her fake assets on, writing "BTS Dolly boobs" and "Thank You for letting me borrow your rack," as she tagged Sara Moonves, the Editor-in-Chief of W Magazine.

As Parton's iconic tune "9 to 5" played in the background, Wilde sipped a drink from a glass as she peddled the machine in Giuseppe Zanotti BEBE Gold Metallic Leather Platform shoes. "In my mind this is how she works out," Wilde wrote alongside the post, also adding that she "fell off shortly after" the video was captured.

Theo Wargo/Getty Wearing a blue and white dress reminiscent of the one that Judy Garland wore as Dorothy Gale in the popular film, Styles completed his look on Saturday with rosy red cheeks, red tights and a matching bow in his hair — alongside a pair of ruby red Gucci slippers, of course! While Styles performed, a picnic basket and a fake dog meant to look just like Dorothy's Toto from the movie also sat beside the former One Direction member onstage. And staying true to character, Styles also sang his own rendition of "Somewhere Over the Rainbow" from The Wizard Of Oz, alongside staple performances of songs already featured on his setlist, including "Watermelon Sugar" and "Golden."
