Halloween sneaks up on us every year, doesn’t it? One second you’re sipping pumpkin spice lattes, the next you’re frantically scrolling Pinterest like, “What do I even wear?!” Been there. Honestly, the struggle is real when you want something cute, creative, and — let’s be honest — Instagram-worthy.
If you and your bestie are on the hunt for aesthetic Halloween costume ideas for best friends that are both trendy and easy, I’ve got you. These looks are stylish without requiring a full Broadway costume budget (because who has time for that?). Grab your coffee (or candy corn, no judgment) and let’s brainstorm together.
1. Angel & Devil Duo
Classic? Yes. Overdone? Maybe. Still aesthetic? Absolutely.
The beauty of this combo is that it’s endlessly customizable. Go minimal with sleek outfits in white and red, or go dramatic with feathers, glitter, and over-the-top wings. One of you gets the halo, the other gets the horns—balance restored.
Why it works so well:
- Contrast makes it pop in photos.
- Super easy to DIY.
- Everyone immediately “gets it.”
Ever noticed how people secretly love labeling themselves as the angel or the devil friend? Yeah, this costume basically does the work for you.
2. Sun & Moon Vibes 🌙☀️
Okay, hear me out: this is like Angel & Devil but with celestial energy. One of you rocks warm golds, yellows, and glowy makeup for the Sun, while the other goes for silvers, blues, and dreamy sparkle as the Moon.
You don’t need to buy full costumes either. A gold slip dress and silver skirt set will nail the vibe with a little shimmer spray.
Bonus tip: Draw little stars and sun rays around your eyes with eyeliner for that Pinterest-y aesthetic. Instant cosmic queens.
3. Clueless-Inspired Cher & Dionne
Ugh, as if! Tell me this isn’t the ultimate best friend Halloween look.
Cher’s yellow plaid suit + Dionne’s black-and-white outfit with the iconic hat = instant recognition. Plus, it’s actually comfy (because let’s be honest, no one wants to spend the whole night adjusting itchy wings).
Why this costume slays:
- It’s 90s nostalgia wrapped in aesthetic perfection.
- People will immediately quote lines at you.
- You’ll look like you walked straight out of a movie scene.
FYI, I once wore the Cher outfit to a party, and someone legit asked me if I was in a reboot. So yeah, it’s that convincing.
4. Barbie & Bratz Dolls
This one screams TikTok aesthetic. One of you goes classic Barbie vibes (pink everything, sleek ponytail), while the other embodies Bratz energy (bold makeup, sass, chunky boots).
You don’t even need matching outfits—just commit to the personality. The contrast between polished Barbie and edgy Bratz makes the whole look pop.
Pro tip: Use bold lip gloss and exaggerated eyeliner for the Bratz half. For Barbie, soft curls or a high pony nails it.
5. Fairycore & Cottagecore Besties
If you and your best friend live on Pinterest boards (guilty 🙋♀️), this is your time to shine.
- Fairycore Bestie: Think wings, pastel dresses, glitter freckles.
- Cottagecore Bestie: Flowy floral dress, straw hat, maybe even carry a fake basket of bread. (Yes, bread. It’s a vibe.)
Together, you look like you stepped out of an aesthetic TikTok filter. And honestly? You kind of did.
6. Wednesday Addams & Enid Sinclair
Straight from Wednesday on Netflix, this is the ultimate “opposites attract” BFF look.
- Wednesday: All-black everything, braids, blank expression.
- Enid: Pastel rainbow sweater, colorful hair clips, bubbly vibe.
This duo doesn’t just scream trendy—it whispers “we actually watch good shows.” Plus, everyone will immediately clock who’s who, no explanation required.
7. Mermaid & Sailor
I know, I know—this one sounds old school. But picture it with a modern aesthetic spin.
- Mermaid look: Iridescent sequins, ocean-colored makeup, glitter highlighter.
- Sailor look: Striped shirt, sailor hat, cute navy skirt.
It’s the contrast (again) that makes this one pop. And come on—mermaids never go out of style. Ever.
8. Matching 2000s Pop Stars
Think early Britney, Christina, or Destiny’s Child vibes. Metallics, rhinestones, low-rise pants, butterfly clips—the whole Y2K dream.
This one works great if you’re in a bigger group too, but even as a duo, it’s instant nostalgia. You’ll look like you just stepped off MTV’s TRL.
Why I love this one: You can literally thrift the entire outfit, and it still looks intentional because that’s exactly the 2000s vibe.
9. Euphoria-Inspired Looks
Say what you want about Euphoria, but the fashion? Iconic.
Each of you can pick a different character—Rue’s grungy hoodie vibe, Maddy’s glitter cutout dresses, Cassie’s soft pastels. Or, just do generic “Euphoria makeup aesthetic” with rhinestones, bold eyeliner, and sparkly dresses.
Why it works:
- You get creative freedom.
- Everyone recognizes the inspiration.
- The makeup itself steals the show.
Just don’t blame me if it takes you an hour to peel rhinestones off your face at 2 a.m. Been there.
10. Corpse Bride & Victoria
For the spooky-yet-beautiful vibe, this Tim Burton-inspired duo takes the crown.
- Corpse Bride: Tattered dress, blue makeup, dramatic veil.
- Victoria: Soft Victorian-style gown, simple curls, neutral makeup.
You get one friend bringing ethereal creepiness, the other balancing it out with delicate elegance. Together? Absolute Halloween perfection.
Extra Tips for Nailing Aesthetic BFF Costumes
- Coordinate but don’t clone. The best duos complement each other rather than copy each other.
- Hair + makeup = half the costume. Don’t underestimate eyeliner, glitter, or wigs.
- DIY saves money. Most of these looks can be pulled from your closet with a few accessories.
- Confidence sells the costume. If you own it, no one cares if your halo is from Dollar Tree.
Ever noticed how the people with the simplest costumes sometimes get the most compliments? Yeah, it’s all in the attitude.
Final Thoughts
Halloween doesn’t need to be stressful or expensive. With a little creativity (and maybe some last-minute Amazon Prime magic), you and your bestie can totally rock an aesthetic Halloween costume that’s trendy, easy, and totally Instagram-worthy.
So, whether you’re feeling angelic, witchy, celestial, or straight-up 90s fabulous, there’s a duo idea here that fits. Honestly, the hardest part will be deciding which one to commit to.
