1. Ferris Bueller & Cameron

If you love Ferris Bueller’s Day Off, then this iconic duo reference is perfect for you and your friend to recreate. Both of these outfits are easy to pull together. Thrift the iconic leopard vest and jersey, or find something similar.

2. Beanie Babies

Feeling nostalgic? The true millennials and older Gen Z remember the original Beanie Babies — in fact, we collected them. To make this outfit personal to each of you, choose a couple of TY Beanie Babies you loved growing up, coordinate outfits, and DIY the iconic TY tags.

3. Mario & Luigi

Mario and Luigi are one of the most famous duos all over the world. If you love Nintendo and grew up playing Super Mario Bros, then this would be a great costume option to try this year. Plus, it’s super simple to recreate — decide who’s going to be who, and all you need are a red and green shirt and hat with a pair of jeans or denim shorts.

4. Serena & Blair

Recreate the infamous bestie duo — Serena and Blair — this Halloween. Make sure to dress in preppy schoolgirl clothes and shoes. Maybe even wear a wig or two to really get into character.

5. Buzz & Woody

Toy Story 5 was released this year, and it reminded us of how special Buzz & Woody truly are. To channel the movie, one of you dresses as Woody (in a copyboy outfit and badge) while the other one dresses as Buzz (in a space fit and silver boots).

6. Maddie & London Tipton

Live the “Suite Life” and dress up as Maddie and London Tipton. I can totally envision getting into character in this outfit, no matter who I choose to be in the duo. It would be such a cute costume to recreate. London Tipton is obviously dressed in a sparkly dress, and Maddie’s character needs her iconic plaid skirt and Tipton hotel outfit.

7. Zach & Cody

McKenzie and I are actually thinking of recreating this costume this year. Being twins, we think it would be hilarious to recreate. Whether you have a sister or a friend, this costume would turn heads and make people laugh.

8. Mia Thermopolis and Lilly Moskovitz

My twin sister and I dressed up as Mia Thermopolis a few years ago. One of us was the “before” version of her, and the other was the princess version. If we were to channel that movie again, we would definitely dress up as Mia and Lilly. It’sthe perfect costume for a bestie duo, too.

9. Clueless Duo Costumes

If your Halloween motto is “dress to impress,” you seriously can’t go wrong with Cher and Dionne. Their iconic plaid outfits have been inspiring costumes for decades—and they’re still just as cute today.

10. Parent Trap Twins

Whether you’re twins or best friends, dressing up as Annie James and Hallie Parker is so simple to do. It’s a great last-minute costume that doesn’t require a lot of effort. Don’t forget to print out the torn picture of your parents on the boat.

11. Rachel & Monica

There aren’t many TV show characters as well-known as Rachel and Monica. In order to truly make this costume come to life, pretend you’re back in Central Perk. Monica is dressed in a simple 90s outfit, and Rachel is working the coffee shop in her apron and coffee mug in hand. To make this any better, you could even buy wigs that mimic their hairstyles in the show.

12. Black Swan Duo Costume

Looking for a Halloween costume that’s effortlessly beautiful? This black and white swan duo is always a showstopper. The contrasting looks make for unforgettable photos and an effortlessly chic costume idea.

13. NYC Tourist Duo Costume

If you’re searching for a unique Halloween costume no one at the party will have, it’ll most likely be this one. A tourist and the Statue of Liberty will make for a show-stopping costume idea for a Halloween party this year. I can only imagine how much fun it would be!

14. ABBA Costume Duo

Sabrina Carpenter is truly the queen of Halloween costumes, and when I saw her recreate ABBA, I was instantly obsessed. Plus, it’s a super easy outfit to throw together. They sell the iconic T-shirt dresses to order online, and all you need are a pair of tall white boots to complete the ensemble.

15. Curious George Duo

Curious George may be known for getting into trouble, but that’s exactly what makes this costume duo so fun. Pair him with the Man with the Yellow Hat for a best friend Halloween costume that’s cute, nostalgic, and full of personality.

22. Rory & Lorelai

There’s truly nothing quite like an early 2000s reference costume, and Rory and Lorelei are probably one of the most recognizable duos of the time period. There are several angles you could take with this, but nothing is more recognizable than Lorelei’s tie-dye top and brown jacket. For Rory, opt to wear her school uniform or a cozy fall sweater, jeans, and a book in hand.
