Olivia Rodrigo Delivered 8 Trippy Halloween Costume Ideas in Her New "Brutal" Music Video

If ever there was an homage to Lilly from The Princess Diaries or Miranda from Lizzie McGuire, Olivia Rodrigo's new "Brutal" music video is it. Overflowing with teen angst and enough early 2000s nostalgia to make our heads spin, the video takes us through the chaos of Rodrigo's Hannah Montanta-esque life, marking every meltdown with a new 2000s-themed hairstyle. And her hot pink clip-in highlights are just the beginning.

To kick off the video, Rodrigo poses as a ballerina in a powder-blue wig with micro bangs before swapping the look for a blond bob, followed by space buns and a wavy red bob à la Ginger Spice. Channeling her punk rock cheerleader from the "Good 4 U" music video, Rodrigo also lets her inner Avril Lavigne take over for a messy pigtail look complete with flower barrettes that even Cher Horowitz would have to admit make her look like one badass betty.
