These 2000s Halloween Costume Ideas Channel Y2K in The Best Way

Let's not play ourselves—there's no other decade quite like the 2000s, which is probably why '00s decade Halloween costume ideas are hotter than low-rise jeans and velour track suits right now. Affectionately, the early Aughts were primetime for fashion—whether that came from style trends, what celebs were wearing at the time, or classic '00s movies and TV shows. Think Jennifer Lopez serving plunging Versace, Aaliyah dancing in a diamond-studded bra, and a red latex body suit that still lives rent-free in every millennial's mind to this day. Truly, the iconic moments go on and on.

If you're a '90s baby through and through (where all the TY Beanie Babies collectors at?!) or maybe you harbor a genuine appreciation for the time, keep reading for the 19 best '00s decade Halloween costume ideas that will rock your world.

19 Best '00s Decade Costumes for Halloween

1. "Oops!...I Did It Again" Music Video Red Stretch Vinyl Catsuit, $144.50+ on Etsy

Name a more iconic pop star of the early 2000s—oops!... You can't! Britney Spears didn't just give us music; she served ~lewks~, honey, lewks that are still relevant and trend-setting to this day, years later. And perhaps there's no other music video style more memorable than her head-to-toe red latex catsuit from 2000's "Oops!... I Did It Again."

This Red Stretch Vinyl Catsuit from Etsy is the real deal. From the second you adhere this bad-boy onto your body (and trust—it'll take you at least 10 to 15 minutes), you'll feel transported to Mars. Bonus points for pairing it with black platforms and a replica of the Heart of the Ocean necklace from Titanic. (You know, because the little old lady dropped it in the ocean in the end, and well, baby, he went down and got it for ya.)

2. Aaliyah Costume, $96.47+ on Etsy

Rest in peace, baby girl. Aaliyah may have only been in the industry for a few short years before she tragically passed away—after all, she was only 22 when she died—but her style, music and unparalleled swag have certainly left their mark on us all.

Recreate Aaliyah's tomboy-bad-girl musical persona with this near-exact replica of her 'fit from the "Try Again" music video. Glitter bra and all.

3. Anchorman Ron Burgundy Costume, $79.99 on Amazon

Ron Burgundy's signature style is pretty hard to miss, which is great news for Anchorman fans. After all, it makes him easy to replicate!

This head-to-toe scarlet suit—complete with matching tie, wig, press-on mustache, press badge and a lapel pin—will get you into character immediately. Just don't punch anyone in the ovary.

4. The Fairly OddParents' Trixie Tang-Inspired Long Sleeve Turtleneck Crop Top, $10.99 on Amazon

Side character (and long-term Timmy Turner love interest) Trixie Tang definitely didn't get the credit she deserved back when she appeared on The Fairly OddParents from 2001 to 2017. But in recent years, millennials have exhibited a growing appreciation (not sure why, though?) for the cartoon character and thankfully, that includes an appreciation for her mod-inspired, lavender outfit.

Just like Trixie Tang, keep it simple with a light purple turtleneck. Don't forget to cake on the lilac eyeshadow to match!

Urban CoCo Women's Basic Versatile Stretchy Flared Casual Mini Skater Skirt, $15.85 on Amazon

Truth is, Trixie was wearing skater skirts well before Ariana Grande was ever on Nickelodeon! This white one is a near-perfect match.

Funtasma by Pleaser Women's Gogo-300 Boot, $49.15+ on Amazon

Your '00s decade Halloween costume wouldn't be complete without Trixie Tang's signature white go-go boots.

5. AOL Instant Messenger Icon—Full Bodysuit Unisex Spandex Stretch Adult Costume, $29.99 on Amazon

Did the Sign On and Sign Off sounds just automatically play in your head? That's how you know you were totally an AIM-er back in the day. Why not pay homage to the little yellow icon that symbolizes our youth spent writing Away Messages and perusing chat rooms?

Slap on a good old-fashioned bodysuit and get in the running man position. When someone asks you who you are for Halloween, expect a chuckle when you give them the answer.

6. Zenon: Girl of the 21st Century Nebula Costume, $54.95 on Etsy

Quite literally, Zenon was ahead of her time. And though she saved Earth—and her own orbiting space station—like, multiple times, it's her bestie Nebula whose style makes our heart go zoom, zoom, zoom, boom, boom, boom.

Raven Symone may have played the second-fiddle bestie to Zenon in Zenon: Girl of the 21st Century on Disney Channel, but to us, Nebula totally had main character energy. Just check this bright pink and blue get-up for proof. Now, that's out of this world!

7. Bring It On Clovers Cheerleader Costume, $39.99 on Amazon

Undoubtedly the biggest rivalry of the early Aughts was between the East Compton Clovers and the Rancho Carne Toros. Well, maybe not their schools, but definitely their cheerleaders. Still a classic to this day—whether or not you enjoy the sport of cheerleading—emulating the fashions of Bring It On will always score you points on the mat.

This Clovers' cheerleading uniform pretty much says it all. I said, brrrrr!

Bring It On Cheerleader Costume for Women, $39.99 on Amazon

Support the Toros (but not their heinous former captain Big Red) by wearing the black-and-white cheerleading uniform of Rancho Carne High School.

8. Penny Proud from The Proud Family Short Sleeve Dress, $54.95 on Easy Cosplay Costumes

Family every single day and night! Penny Proud was a force to be reckoned with when The Proud Family aired on Disney Channel from 2001 to 2005. And her style? So chic and so ahead of its time.

Copy Penny's signature style with the Penny Proud Short Sleeve Dress from Easy Cosplay Costumes. Just be sure to part your hair into two pigtails!

9. The Hangover Alan Deluxe Costume Set, $64.95 on Amazon

No offense to Phil, Doug, and Stu but Alan—hands down—has the most memorable style of all The Hangover crew. All you really need is the baby carrier and you're set!

This epic Hangover costume comes with the licensed t-shirt, glasses, a baby carrier with a fake Carlos baby, a wig, beard and mustache. Just like that, you're one-fourth of the Wolf Pack!

10. Jenna Rink's 13 Going on 30 Replica Dress, $30 on Etsy

The perfect '00s decade Halloween costume doesn't exi—. Oh wait, it's Jenna's signature dress from the Poise magazine party. The dress of our literal dreams since 13 Going on 30 came out in 2004. Just don't forget the Razzles!

11. J.Lo's 2000 Grammy Awards Look—Nights In Paradise Printed Maxi Dress, $69.99 on Fashion Nova

Before we winged our liner up to the gods, Jenny from the Block went the opposite way and rocked the most iconic plunging neckline to date. It's safe to say that no one could look away from her Versace masterpiece during the 2000 Grammy Awards. Including her now-husband Ben Affleck...

Waiting for tonight? No sweat. Love don't cost a thing but this Fashion Nova dress—inspired by the original Versace gown that rocked the nation—is under $70.

12. Britney Spears Y2K Award Show Costume Set, $68 on Dolls Kill

*Sighs.* A timeless moment in '00s fashion that simply can't be outdone, Britney and Justin Timberlake set the bar way, way high when they served this couples' look at the 2001 American Music Awards. Truth be told, the red carpet has never been the same.

We're willing to bet this take on Britney's red carpet look isn't real denim, but it certainly gets the job done. The Halloween costume comes with a strapless crop top, a low-rise maxi skirt, a rhinestone choker, bracelet, chain belt and a mini bucket bag. Now all you're missing is the pre-"Cry Me a River" arm candy.

Justin Timberlake-Inspired Men's 2 Buttons Denim Blazer Lapel Washed Denim Suit Jacket, $55.98 on Amazon

In this denim blazer, your partner can convincingly play the part of the JT to your Britney, b---h.

13. Napoleon Dynamite Complete Costume Kit, $54.95+ on Amazon

Napoleon Dynamite was definitely an anchoring moment in time for movie-watchers when it premiered in 2004. You know you either had or wanted a "Vote for Pedro" t-shirt back in the day.

The complete Napoleon Dynamite costume kit comes with slip-on boot overs, a wig, glasses and the VFP shirt.

14. Destiny's Child "Survivor" Music Video—Leg Avenue Women's 2 Piece Goin' Commando Costume, $79.99 on Amazon

When you think of Destiny's Child circa 2001, you think of the "Survivor" music video, don't you? (Sure, we love "Say My Name" and "Bills, Bills, Bills" but both were before the best-selling girl group dropped two of their gals in the 90s.) But, you know, Kelly, Michelle, and Beyoncé... survived.

It's not a carbon copy of the "Survivor" music video looks per se, but the aesthetic is certainly there. Add a few gold accessories, line those lips, and get ready to execute some amazing choreography on the beach. Or you know, go to a Halloween party instead.

15. Regina George From Mean Girls—A Little Bit Dramatic' Glitter Sparkly Hot Pink V-Neck Cropped Fitted Tank Top, $22.95 on Etsy

Most of us who grew up in the '00s have felt personally victimized by Regina George at one point or another. But that doesn't mean we can't dress up like her! The queen of the Plastics is known for a pretty basic 'fit, but we highly recommend pairing it with a Starbucks cup and a tiny purse for more authenticity.

Would wear this every other day of the year, TBH, not just on Halloween.

Regina George-Inspired Tsher Women's Waist Pleather Skirt, $18.19 on Amazon

Almost identical to the faux leather skirt Regina George wears in the movie, all you need now is a straight, blonde wig.

16. Mugatu Zoolander Rubie's Costume, $45.86+ on Amazon

Blue steel, anyone? Make sure to purse your lips all night if you're going to recreate this famous 2001 movie look popularized by Ben Stiller. This Zoolander-inspired Halloween costume will make all other Halloween costumes put a cork in it, Zane!

17. Avatar's Neytiri—Rubie's Adult Deluxe Costume Wig, $26 on Amazon

When Avatar debuted in 2009, it smashed box office records including outselling Titanic's lifetime earnings. And it's not hard to see why. Plot lines aside, Avatar has become a fan favorite amongst cosplayers and Halloween enthusiasts looking for a costume. Why? Blue skin! Wigs! Makeup!

Pair the Rubie's Avatar Neytiri Adult Deluxe Costume Wig with a bright blue bodysuit and you're as good as native Na'vi. Well, not quite, but it can be fun to pay homage to one of the bestselling movies of all time!

18. Elle Woods in Legally Blonde—California Costumes, $64.99 on Amazon

When Elle Woods (and Bruiser Woods) took on the Harvard campus in 2001, the world got iconic gems such as "the Bend and Snap!" and "What, like it's hard?" Suffice it to say we haven't been the same since and to this day, we hope Warner Huntington III is out there miserable somewhere. While you don't need a law degree in order to channel Elle Woods' pink-on-pink aesthetic, if you dress up as Legally Blonde this Halloween, just remember the cardinal rule of perm maintenance: "You're forbidden to wet your hair for at least 24 hours after getting a perm at the risk of deactivating the ammonium thioglycolate"

Whoever said orange is the new pink was seriously disturbed, so shop this all-in-one Halloween costume that includes the pink dress, jacket, and of course, Elle's handbag and dog.

19. TLC Girl Group Costume—Mesh Crop Top Without Bra, $4 on SHEIN

Girl group TLC did so much for music—and fashion—during the '90s and early '00s prior to Lisa "Left Eye" Lopes perishing in a tragic car accident. The crazy, sexy, cool way the trio challenged gender stereotypes and embraced a new kind of style turned heads everywhere and makes them a great Halloween option for any threesome.

For one infamous TLC look, each TLC member wore coordinating Tommy Hilfiger 'fits for each color of a traffic light: red, yellow and green. A mesh top in either red, yellow or green will get the job done for this quick DIY costume.

Men's Underwear Athletic Knit Boxer, $25 on Macy's

All you really need is for the main Tommy Hilfiger band and the initial color of the boxers to show. Don't worry—it's just the aesthetic!

Men's Champion Cinched Jersey Pants, $24.99 on Kohl's

Complete the look with black Champion sweats... Just make sure you can see the waistband of the Hilfiger undies!
