11 Y2K Fashion Halloween Costumes To Shop Now

Imagine it’s 2008, and you just turned on your television to see yet another rerun of Mean Girls. After grabbing some popcorn and tuning into Regina George’s snarky remarks (which, by the way, you memorized word-for-word), you finally changed the channel and just so happened to stumble upon VH1’s throwback music countdown. Luckily for you, you were able to jam out to Avril Lavigne’s “Sk8r Boi” for the umpteenth time. In the end, you finally settled on Disney Channel right when that catchy original theme song plays for movies like Cheetah Girls and Lizzie McGuire before dozing off on the couch (and, of course, your mother scolded you to go sleep in your room). Wow, am I the only one who misses this part of my childhood, minus the scolding?

“Spooky Szn” is already upon us, and what better way to celebrate Halloween this year than to relive some of Hollywood’s best moments from the early 2000s? With the resurgence of Y2K fashion trends, there's nothing better than to dress up as the epitome of early-aughts nostalgia.
