Are you and a best friend literally attached at the hip? Okay, not literally, but you get what we mean! We’ve debated and deliberated and we decided that having a bestie in high school is actually more vital than owning a cell phone. Allow us to explain…. Who else are you going to pass notes to when you’re sitting in Chemistry class bored out of your mind? Your BFF of course. Plus, it’s not like you could eat a tub of chocolate frosting in your PJs while binge-watching The Vampire Diaries with just anyone! You need your ride-or-die sister-from-another-mister by your side to partake in all of your slightly awkward favorite activities. In fact, you need your other half with you to partake in everything you do, even Halloween! It's obvious your bestie is vital to your very existence (that might be a slight exaggeration, but you understand), so we’ve conjured up some of our cutest costumes for BFFs. We have tons of options to fit all kinds of bestie relationships so pick out your favorite, put it on, and start posing for some Instagram posts. Your "likes" are going to skyrocket!

You have to admit: Chucky and Tiffany are totally relationship goals… well, that's if you can ignore the epic killing spree the pair go on!

Outfit yourselves as Alice, the Cheshire Cat, and Mad Hatter and watch your fanciful evening unfurl right before your very eyes!
17. Finding Nemo Costumes: Dory and Nemo

Make sure you really swish those fins while you're rocking these Nemo and Dory costumes. Oh, and if you happen to see a really big boat out in the distance, don't go and touch it. We would hate to see you two get separated!
18. Orange Is the New Black Costumes: Piper and Alex
| Orange Prisoner Costume | Black Glasses |
Piper and Alex have a pretty complicated relationship: sometimes they’re enemies, sometimes they’re besties, and sometimes well, they’re much more than friends! Anyway, if you two are partners in crime who can’t get enough of the juicy HBO series, Orange Is the New Black, then why not become Litchfield Penitentiary’s most popular couple? Shackle yourselves up in orange jumpsuits, and be sure to add a pair of black frame glasses for the Alex costume!
19. Shego and Kim Possible Costumes
| Kim Possible Costume | Shego Costume |
Be the most iconic pair of frenemies with these Kim Possible costumes! One of the most iconic Disney cartoons of the 2000s, Shego was one of the few supervillains who could keep up with Kim Possible. Kim Possible herself is also easy enough to DIY, but you can step it up a notch by changing your ringtone to the one on Kim's phone. What's the sitch?
20. Romy and Michele Costumes
| Romy Costume | Michele Costumes |
Being friends doesn't mean that you never fight. However, besties can make amends, just like Romy and Michele! Just as they discovered for themselves, it's better to be authentic than to fake your way to fame. In the end, they still managed to dress to impress. Don't forget to show off your best moves at the Halloween party! (If you can get them to play "Time After Time" by Cyndi Lauper, you can recreate the iconic scene from the movie!)
21. Mean Girls Costumes
| Regina George | Karen Smith | Gretchen Wieners |
On Wednesdays, we wear pink. Are you ready for some Mean Girls costumes? The core group of plastics included Regina George, Karen Smith, and Gretchen Wieners before Cady came onto the scene. They had clearly been friends for a while, as they were always well-coordinated, even down to their sexy Halloween costumes! (Poor Cady didn't get the memo.)

Did you grow up together with your best friend? Then perhaps a Bambi and Thumper costume is just what the two of you need!
