She loves a great Oprah viral moment and all things Netflix—but come summertime, Big Brother has her heart. I love a camp classic, I just never thought of Bring It On that way—at least until much much later when I saw whole parties where people would dress up as the Toros and Clovers and do all the dances. If you’ve seen the film, you can probably finish the rest of the cheer, because 20 years later, the opening of Bring It On remains one of the most indelible teen moments of the early aughts.

To celebrate the anniversary of the teen classic, Union told Vogue what went into filming those intricate routines, problematic dialogue she asked the filmmakers to change, and why Universal Pictures wouldn’t lend her the original Clovers’ uniform for Halloween. As the costume designer behind the other most popular film of the time, Mean Girls, she has experience with that. The script was a little cringe-y, so when they offered me the job, I said, “Can we make some changes? This was meant to contrast the look of Missy (Eliza Dushku), the new girl who transfers from a school in Los Angeles and, at first, is hesitant to join the team. The cast of breakout stars also featured Eliza Dushku and Jesse Bradford with future Ant-Man director Peyton Reed at the helm.With a rough idea in mind, Fort’s main job as the costume designer was coming up with opposing team looks for the Toros and Clovers, differentiating their two styles and giving their uniforms a distinctive vibe. She comes from Los Angeles, and I know it’s only a 100 miles away, but there’s a world of difference. It should be noted that the mostly-open cardigan with nothing underneath, seen below, is one of the biggest trends of this summer.

With Union’s performance steering it, Bring It On ushered in a bolder, more socially conscious era for teen comedies, foregoing white-savior tropes and sharply dissecting female rivalry. Two decades later, the movie’s epic dance routines and memorable one-liners are completely unforgettable. A denim skirt is a staple, while Torrance's pink crop top would pair well with almost any type of bottom. Two decades later, the fashion of Bring It On feels somehow even more on-trend today than it did when it came out.If you're cosplaying as a "Bring it On" cheerleader this Halloween, you might be wondering how you should act at the party to really bring your character to life. They had to complement each other without matching, without competing, and both had to be noticeable. Prior to signing on to the project, Fort was completely unfamiliar with the world of competitive cheerleading.
