DIY Halloween Costume Ideas for Best Friends 🎃👯‍♀️

You and your best friend could visit a big box store, grab a polyester costume, and call it Halloween.

But where’s the fun in that? DIY Halloween costumes for best friends are cheaper, more enjoyable to create, and full of personality.

Plus, they look great on Instagram! Crafting together builds lasting memories.

Honestly, nothing bonds friends like trying to hot-glue something at 1 a.m. without sticking your fingers together.

I’ve made DIY costumes with my BFF since high school. We’ve tackled everything from simple pun costumes to wild themed looks.

Some turned out Pinterest-perfect. Others were, let’s say, “creative.” 🙂 No matter what, they always got people talking. That’s the goal, right?

Now, let’s explore 11 budget-friendly DIY Halloween costume ideas for best friends that will make people say, “OMG, how did you think of that?”

1. Peanut Butter & Jelly — The Classic Duo

You already finish each other’s sentences, so why not sandwiches?

Supplies: Brown T‑shirts, purple felt, tan felt, fabric glue.
How to make it: Cut bread shapes from tan felt and “spread” one shirt with purple felt jelly, the other with brown felt peanut butter.

Why it works: Everyone gets the joke instantly. Bonus points if one of you carries a butter knife (fake, of course).

Pro tip: Go extra with matching sneakers in jelly or peanut butter colors.

2. Sun & Moon — Celestial Chic

Bring balance to the costume party.

Supplies: Gold and silver clothing, cardboard, metallic spray paint, glitter.
DIY magic: Cut a giant sun and crescent moon from cardboard. Spray, glitter, attach to headbands.
Why it works: It’s artsy, photogenic, and works for totally different style vibes.

Hot take: The “moon” person always ends up being mysterious. Don’t ask me why — it’s a cosmic law.

3. Mermaid & Sailor

One’s whimsical, the other’s ready to “man” the ship.

Supplies: For the mermaid — sequin skirt, seashell bra or T‑shirt, netting. For the sailor — navy pants, striped top, sailor hat.

Why it works: The contrast makes it pop, and you can add ocean‑themed props.

4. 90s Sitcom Icons

Channel your inner Will & Carlton, Rachel & Monica, or Kenan & Kel.

Supplies: Thrift store treasures — think overalls, scrunchies, big blazers, patterned shirts.

Why it works: Nostalgia wins every time. Plus, comfy clothes all night.

5. Angel & Devil — With a Twist

Go subtle and stylish instead of cheesy.

Supplies: All‑white and all‑black outfits, gold pipe‑cleaner halo, red horns.

Extra twist: Swap roles halfway through the night — confuse everyone.

6. Bob Ross & Happy Little Tree 🌳

One paints, one is… painted.

Supplies: For Bob — curly wig, button‑up, fake palette. For tree — green top, fake leaves, maybe a few squirrels if you’re extra.

Why it works: Wholesome and hilarious.

7. Ghostbusters 👻

Because someone has to handle the haunted punch bowl.

Supplies: Khaki jumpsuits (or matching khaki pants/shirts), printed Ghostbusters logo, cardboard proton packs.

Fun factor: Everyone will shout the theme song at you at least once.

8. Garden Fairy & Mushroom 🍄

One flutters, the other… sits there looking magical.

Supplies: For fairy — flowy dress, wings, glitter. For mushroom — red beret with white felt spots, neutral outfit.

Aesthetic win: Looks amazing in outdoor, autumn party photos.

9. Mad Scientist & Experiment Gone Wrong 🧪

One’s genius, the other’s glowing.

Supplies: Lab coat, goggles, random props; neon makeup or glow‑stick accessories for the “experiment.”

Why it works: Endless creative options.

10. Pirate & Parrot 🦜

You could both be pirates, but where’s the commitment?

Supplies: Pirate — striped shirt, bandana, fake sword. Parrot — colorful clothing, feather boas, face paint.

Photo factor: People will definitely pose with you.

11. Taco & Hot Sauce 🌮🔥

You bring the flavor, they bring the heat.

Supplies: Felt for taco shells, toppings, and a red outfit with a “Hot Sauce” label.

Why it works: Food costumes = instant conversation starters.

Tips for Pulling Off Your DIY Best Friend Costumes Like a Pro

Plan together, not “I’ll figure mine out later”

I’ve seen BFF duos where one person goes full Oscars red carpet and the other shows up like they stopped at the drugstore 20 minutes ago. Don’t do that to each other. Sketch the outfits, make a supply list, and split the shopping.

Use what you already own

Half the magic of DIY Halloween costumes for best friends is raiding your own closet (and maybe your mom’s attic) before spending a single cent.

Don’t underestimate accessories

The right hat, prop, or weird thrift store scarf can take your costume from “meh” to wow.

Comfort matters

You’ll walk, dance, and maybe even run away from a fog machine. Make sure you can actually move in your costume.

Final Thoughts — Make It Yours

At the end of the night, no one remembers if your halo was perfectly glued or if your fake taco lettuce was slightly crooked. They remember if you laughed, if you owned the room, and if your costume told a story about you.

DIY Halloween costumes for best friends are less about “being perfect” and more about being you, times two. So grab your glue gun, your BFF, and a bag of candy for “creative fuel” — and get ready to own Halloween.
