22 Early-2000s Halloween Costume Ideas

While any Wes Anderson film makes for great costume inspiration, Gwyneth Paltrow's Margot Tenenbaum from "The Royal Tenenbaums" is one of the absolute best. All you need for this early-2000s costume are a blond wig and a fur coat — and plenty of eyeliner.

No matter what phase of Mia's makeover in "The Princess Diaries" you decide to replicate, your costume is sure to be a royal hit. For pre-makeover Mia, tease out frizzy hair and slip on a prep-school uniform.

In the early 2000s, J Lo's famous booty was the face (or bottom?) of Juicy sweats. Break out that velvet tracksuit and some sweet shades to channel the pop star this October.

Britney Spears's most iconic outfits were those worn in her "...Baby One More Time" and "Oops!...I Did It Again" videos. Dress as a sweet schoolgirl or a red space explorer to spark plenty of 2000s pop nostalgia.

Angelina Jolie used her tough-girl qualities to play a perfect Lara Croft in "Tomb Raider." Fake handguns, hiking boots, and some cargo shorts will scare even the toughest villains this Halloween.

To dress up like Raven from hit show "That's So Raven," put on a basic shirt, wear denim on denim, and put your hair up. Just note that while Raven's look is one thing, nailing the Halloween costume is all about perfecting your "I'm having a vision" look.

Meg from "Family Guy" was definitely an early-2000s TV staple. The character's trademark beanie, glasses, and pink tee are all easy to replicate.

The chipper sponge from Nickelodeon's "SpongeBob SquarePants" wears the same outfit every day: a red tie, a white collared shirt, brown pants, and a pair of striped knee-high socks. Become the sea dweller yourself with a yellow T-shirt, a brown skirt (or pants), and striped socks.

Alex, Sam, and Clover, is that you? All you need are green, red, and yellow bodysuits with red, blond, and black wigs to bring these "Totally Spies!" characters to life.

"The Princess and the Frog" is such a sweet Disney movie, and Princess Tiana steals our hearts every time. To dress up as this Disney princess, wear an elegant green dress, a crown, and gloves.

Whether you want to dress up as Isis or any other member of the Clovers cheerleading team from the original "Bring It On," it's pretty easy — just pick up the costume from your local Halloween store. Or better yet, use a green cheerleading suit you already own; just make sure it says "Clovers" on it.
