22 Iconic 2000s Halloween Costumes for a Throwback Y2K Party
If your ideal Halloween already involves low-rise jeans, glittery eye shadow, and the thumping beats of early 2000s pop, this guide is for you. Whether you lived through the era or are discovering it through today’s TikTok viral trends, the Y2K aesthetic is back in a big way. Halloween is the perfect excuse to revisit those unforgettable pop culture moments, movie icons, and trendsetting outfits that defined the early aughts—one Juicy Couture tracksuit and bedazzled choker at a time.
We’ve curated 22 best 2000s Halloween costume ideas to inspire your look. Get ready to channel movie characters, TV stars, music legends, and more for a nostalgia-packed night.
1. Miss Congeniality
Breathe life into Sandra Bullock’s iconic FBI-agent-turned-beauty-queen transformation from the classic comedy Miss Congeniality. Sport a sparkly pink pageant gown, a “Miss United States” sash, and don’t forget combat boots for that undercover flair. A messy updo and some bruised makeup finish off the look for full undercover agent vibes.
2. Mia Thermopolis from The Princess Diaries
Channel your inner Genovian princess by recreating Anne Hathaway’s ‘before’ or ‘after’ transformation as Mia Thermopolis. Go for frizzy hair, glasses, a navy school blazer, plaid skirt, and a tiara—or opt for her sparkling gown, white gloves, and a sophisticated updo for royal perfection.
3. Jenna Rink from 13 Going on 30
Capture the “30, flirty, and thriving” magic with Jenna Rink’s unforgettable rainbow-striped dress from that Thriller dance scene. Pair it with strappy heels, a butterfly necklace, and don’t forget a bold lip for that ultimate early-2000s vibe.
4. Juno
The quirky 2007 indie film Juno offers one of the most instantly recognizable couples’ costumes. For Juno: layer a striped T-shirt under an oversized hoodie, add a pleated miniskirt over cuffed jeans, and sling on a shoulder bag. For Paulie Bleeker: a maroon track shirt, yellow gym shorts, sweatband, and tube socks capture the awkward charm.
5. Kim Possible
Reimagine the cartoon secret agent with a fiery-red wig, a black crop top, olive green cargo pants, combat boots, and some thumb holsters. A toy communicator prop and utility belt round out Kim’s action-ready look. Ready to save the day (and your Halloween party)? Call me, beep me!
6. The Plastics from Mean Girls
This is not a regular costume—it’s a cool costume. Gather your crew to channel Regina, Gretchen, Karen, and Cady. Think pink on Wednesdays: miniskirts, cardigans, high heels, and attitude to match. For solo vibes, go as “Mouse, duh” with black ears, or the bunny outfit from the Halloween party scene.

7. Napoleon Dynamite
Thanks to the 2004 cult favorite, this might be the easiest costume on the list. All you need is a curly-haired wig, nerdy wire-rimmed glasses, straight-leg jeans, and a “Vote for Pedro” T-shirt. Finish it off with some awkward dance moves and a sense of deliberate monotone.
8. Mariah Carey in a Juicy Tracksuit
A Juicy Couture velour tracksuit is the ultimate Y2K status symbol. Channel Mariah Carey’s off-duty glam with a pastel tracksuit, oversized gradient-lens sunglasses, layered chain necklaces, and platform heels. Touch up with frosted lip gloss for the authentic early-aughts finish.
9. Nicole Richie’s Denim Mini and Uggs Combo
Recreate the casual glamour of The Simple Life star Nicole Richie with a frayed denim miniskirt, pastel cami or baby tee, and—of course—Ugg boots. Layer over a chunky cable-knit sweater and accessorize with a trucker hat and oversized sunglasses for the full celeb-off-duty effect.
10. Avril Lavigne
Bring the pop-punk princess to Halloween with a white tank top, loose black cargo pants, skater shoes, and most importantly—a skinny men’s striped tie. Accessorize with black wristbands and smudged eyeliner to finish the sk8r girl look.
11. Destiny’s Child (Survivor Era)
If you have two friends, you can’t go wrong with a coordinated Destiny’s Child “Survivor” music video tribute. Get matching camo-print separates (think bra tops, pants, and boots) and be your own Beyoncé, Kelly, or Michelle for the night.
12. Paris Hilton at Her 21st Birthday
No one embodied early-2000s excess quite like Paris Hilton. Reimagine her infamous 21st birthday look with a metallic pink or silver slip dress, a blinged-out choker, tiara, and rhinestone-studded accessories. Statement platform heels and a small sparkly purse polish off the party queen ensemble.
13. Britney Spears (Oops!… I Did It Again)
Britney defined the Y2K generation. Nail her iconic “Oops!… I Did It Again” red jumpsuit by styling a sleek ponytail, bold eyeshadow, and, if you can, a headset mic for all-night pop star vibes.
14. Christina Aguilera (Dirrty Era)
Bring back Xtina’s notorious “Dirrty” look with black chaps over shorts, a cropped sports tank, fingerless gloves, faux leather details, and metallic eye makeup. Don’t forget the black streaks in your hair or temporary tattoo details.
15. Lizzie McGuire
Disney Channel’s everygirl is all about clashing prints, fun accessories, the classic crimped hair, bell-bottom jeans, and butterfly hair clips. Layer a graphic tee with a colorful tank, flared pants, platform sandals, and finish with plenty of 2000s snacks (Gushers, anyone?) on hand.
16. Elle Woods from Legally Blonde
“What, like it’s hard?” The pinkest costume on the list is Elle Woods’ Harvard debut: a hot pink skirt suit, matching heels, perky blonde curls (wig optional), and a tiny plush Chihuahua for “Bruiser Woods.” Bonus points for carrying her signature pink laptop case.
17. The Royal Tenenbaums: Margot and Chas
This Wes Anderson cult film offers quirky, artsy couple’s costume ideas. For Margot: a blonde wig with a red hairband, a fur coat, striped tennis dress, and heavy eye liner. For Chas: red Adidas tracksuit and a fake Dalmatian pup or two by your side.
18. Lara Croft: Tomb Raider
Channel Angelina Jolie’s action-heroine with a black tank top, khaki shorts, combat boots, a toy pistol belt, and braided ponytail. Go full tomb raider with fingerless gloves, a faux utility belt, and plenty of attitude.
19. Corpse Bride
Turn Tim Burton’s 2005 masterpiece into a hauntingly beautiful costume: long white dress, blue wig or temporary blue hair spray, ghostly face makeup, and a wilted floral bouquet. This look is both haunting and instantly recognizable for film fans.
20. J.Lo at the 2000 Grammys
The green Versace dress became a fashion legend. Find a deep-V green palm print maxi dress (there are costume versions online), style your hair in soft waves, and accessorize with hoop earrings and strappy heels. Prepare for everyone at the party to know exactly who you are.
21. “Bring It On” Cheerleaders (The Clovers or The Toros)
Whether you rep the Clovers or Toros, relive Kirsten Dunst’s cheer-tastic moments. Wear a cheerleader skirt and top set, white sneakers, ponytail, and—most importantly—colorful pom-poms and megawatt smiles. Find a buddy for your perfect spirit duo.
22. Jersey Shore Cast
For the ultimate group costume—and a little self-tanning spray—go as Snooki, Pauly D, The Situation, or any of the MTV wildcards from Jersey Shore. Tight t-shirts, bold animal prints, massive hair, and bronzer complete the “gym, tan, laundry” look.
How to Nail the 2000s Aesthetic
- Fabrics: Go for shiny velour, satin, denim, or metallics.
- Accessories: Trucker hats, rhinestone chokers, butterfly hair clips, and tinted sunglasses were everywhere.
- Footwear: Ugg boots, platform sandals, pointy heels, and skate shoes define the era.
- Makeup: Frosted shadow, pink gloss, glitter, thin brows, and lots of blush. Embrace the shine.
- Layering: Layer tanks over tees, skirts over pants, or cardigans over basically anything.
