This friendship may not survive that debate.

Choose carefully.
This decision could determine who is actually in charge of the friendship.
5. Mario and Luigi
Grab some overalls, hats and mustaches and become the most recognizable video game brothers in the world.

To infinity and beyond!
One friend becomes Woody and the other Buzz Lightyear.
It’s a fantastic costume for best friends who are always together.
And if someone asks which one is the better character, simply refuse to answer.
You don’t need that kind of drama on Halloween.
25. Minions
Why choose just one Minion?
Both best friends can dress as Minions.
Matching costumes are particularly funny when you act like a pair of mischievous Minions throughout the night.

Pick two emojis that perfectly describe your friendship.
Maybe one person is the laughing emoji while the other is the eye-roll emoji.

The possibilities are practically endless.
And if you’re always laughing while your best friend is always judging you, the costume choice is obvious.

One person dresses as Netflix while the other dresses as “chill.”
You can interpret the costumes however you like.
The important thing is that everyone understands the joke.
28. Wi-Fi and No Signal
Perfect for best friends who are always attached to their phones.

The other dresses as “No Signal.”
It’s even funnier if the No Signal costume follows the Wi-Fi costume around all night.
Because apparently even Halloween needs technical difficulties.
29. Plug and Socket
This is another funny costume for two people who are always together.
One person is the plug and the other is the socket.
It doesn’t require much explanation.
You’re a pair.
You belong together.

The other wears “PASTE.”
Simple.
Cheap.
Funny.
And very easy to make yourself.

You could add clouds, stars, sunglasses or a moon to make the costumes more obvious.
It’s a simple idea that can look fantastic in photos.
33. Good Luck and Bad Luck
One friend is Good Luck.
The other is Bad Luck.
This works particularly well if one of you is constantly having things go wrong.
If your best friend trips over something five minutes after arriving, the costume is already working.
34. Brain and No Brain
This one is for friends who aren’t afraid to make fun of themselves.
One friend dresses as a giant brain.
The other wears a sign that says “No Brain.”
It’s especially funny if the No Brain friend is the one who usually comes up with all the terrible ideas.
35. Before and After Coffee
For best friends who aren’t functional before their morning caffeine, this one is perfect.
One friend dresses as “Before Coffee.”
The other becomes “After Coffee.”
The before version should look exhausted.
The after version should look completely unstoppable.
36. Angel and Devil on the Shoulder
Instead of simply dressing as an angel and devil, make the joke more specific.
One person becomes the angel.
The other becomes the devil.
Then spend the evening standing on either side of your third friend’s shoulders and giving terrible advice.
It’s a great group costume too.
37. Macaroni and Cheese
Because best friends belong together like macaroni and cheese.
One person can be the macaroni and the other the cheese.
It’s goofy, recognizable and guaranteed to make people hungry.
38. Hot and Cold

A lock and key costume is a fun way to show that you’re best friends who simply fit together.
One friend becomes the lock.
The other becomes the key.
It’s cute without being overly complicated.
40. Dynamic Duo
Can’t agree on a specific costume?
Make yourselves the Dynamic Duo.
Wear matching superhero outfits, capes and masks and create your own superhero names.
Maybe you’re:
The Snack Defender and The Remote Controller.
Or:
Captain Chaos and The Voice of Reason.
Your best friend will probably know immediately which role belongs to each of you.

- A banana and a vampire
- A chicken and a superhero
- A pumpkin and a shark

You don’t have to explain yourselves.
You’re best friends.
That’s enough.
Tips for Choosing the Best Friend Costume
Before you settle on your Halloween costumes, think about what will actually work for both of you.
Choose something that is comfortable enough to wear for several hours, especially if you’re going to a party.
It’s also worth deciding how much effort you both want to put into the costumes.
One person shouldn’t turn up in a homemade cardboard masterpiece while the other has thrown on a T-shirt five minutes before leaving.
Unless, of course, that’s the joke.
The best costumes are usually the ones where both people are equally committed to the idea.
And if you can make people laugh without needing a ten-minute explanation, you’ve probably found a winner.
Halloween is even better when you have your best friend beside you.
Whether you’re dressing as peanut butter and jelly, Batman and Robin, Mario and Luigi, a pair of emojis or something completely ridiculous that you invented yourselves, a matching costume gives you twice the opportunity to have fun.
And don’t worry about finding the most elaborate costume.
Sometimes the simplest ideas are the funniest.
After all, you don’t need expensive costumes to prove you’re best friends.
You just need one terrible idea…
and a friend willing to wear it with you.
Happy Halloween, besties!
