So, you’re a brunette with long, luscious hair and you’re stressing over Halloween costume ideas? First off—relax. You’re literally sitting on a built-in accessory that most wigs can only dream of. Dark hair automatically gives you a ton of Halloween costume options that look instantly iconic. Whether you want spooky, sultry, or straight-up hilarious, your long brunette hair has your back (and your head).
I’ll be honest—I’ve been there. I’ve spent hours scrolling costume sites only to realize that most “one-size-fits-all” ideas look way better on brunettes with long hair. Why? Because dark hair instantly adds depth, drama, and mystery to a look. And if your hair naturally cascades down your back, you’ve already got a “main character energy” vibe that costumes can enhance like crazy.
Ready to find out which looks will actually turn heads this Halloween? Let’s break down the 12 best Halloween costumes for brunettes with long hair—complete with my tips, sarcasm, and all the hair-flipping glory you deserve.
1. Morticia Addams
Come on—did you even Google “Halloween costumes for brunettes with long hair” if Morticia isn’t your first thought?
- Long, silky black hair: check.
- Red lipstick that screams “don’t mess with me”: check.
- A sleek black gown with dramatic sleeves: double check.
The best part? You don’t even need to fuss much. Just straighten your hair, wear a gothic dress, and give people that death stare. Boom—you’re Morticia.
2. Wonder Woman
Brunettes, unite—because Wonder Woman was basically designed for us. The character’s iconic look pops the most with long, dark hair flowing behind her.
- Grab that golden tiara (yes, Amazon sells them).
- Rock a red corset or top, blue skirt/shorts, and gold cuffs.
- Let your brunette locks do the rest.
Trust me, nothing feels more badass than swishing your hair around while pretending to deflect bullets.
3. Cleopatra
If you’ve got dark brown hair, you’re already halfway to Cleopatra queen energy. Straighten your hair, or braid small sections, then layer it with golden accessories.
Pro tip: add a blunt cut wig with bangs if you want to go full traditional Cleopatra, but if you keep your natural hair, it still looks regal and modern. Plus, gold eyeliner? Automatic slay.
4. Wednesday Addams (All Grown Up)
Yes, Wednesday usually rocks braids—but guess what? If you’ve got long brunette hair, you can absolutely reinvent her look.
- Part your hair down the middle, do two neat braids, and keep it simple.
- Wear a black collared dress with white accents.
- Walk around looking annoyed at everyone.

I once dressed as Wednesday, and honestly, it was the easiest “low-effort, high-recognition” costume I’ve ever done. Everyone got it immediately.
5. Witchy Vibes (Pick Your Own Style)
Sometimes, the best costume is a flexible one. A long-haired brunette as a witch? Classic. But the fun part is that you can make it your own.
Want to be a sexy witch? Grab a corset and thigh-high boots.
Want to be a scary witch? Add a long black cloak and smoky makeup.

Want to be a cottagecore witch? Throw on a flowy dress and carry a crystal ball (or, let’s be real, a Starbucks cup).
Your long hair is the perfect foundation—straighten it for sleek vibes, curl it for mystical energy.
6. Bellatrix Lestrange
Harry Potter fans will bow down when you show up as Bellatrix. Her messy, wild brunette curls are half the character.
- Tease your hair like it’s auditioning for a ‘90s hair commercial.
- Smudge some eyeliner for that unhinged vibe.
- Wear a long, dark gown with a wand in hand.
Ever wanted to walk around saying, “I killed Sirius Black!” dramatically? Now’s your chance.
7. Lara Croft
Not into gowns and dramatic flair? Go action-hero chic. Lara Croft from Tomb Raider looks incredible on brunettes with long hair.
- Pull your hair into a messy braid or ponytail.
- Wear a tank top, shorts, and boots.
- Add toy guns or a backpack for authenticity.
IMO, Lara Croft is perfect if you want a costume that’s equal parts practical and badass. Plus, no one can trip you up in combat boots.
8. Elvira, Mistress of the Dark
Okay, hear me out: Elvira is basically Morticia’s sassier cousin.
- Big, teased brunette hair (the higher the hair, the closer to… Halloween?).
- A sultry black dress with a deep neckline.
- Over-the-top makeup that says “I own the night.”
Elvira costumes are super fun because you get to embrace campy, cheeky vibes. And brunettes with long hair pull this off without even trying.
9. Esmeralda (Disney’s Hunchback of Notre Dame)
Want something colorful and fun instead of all-black goth glam? Go Esmeralda.
- Flowing brunette hair? Perfect.
- Big hoop earrings, a white blouse, and a purple skirt.
- Add a tambourine if you’re extra.
Esmeralda works beautifully if you want a Halloween look that’s romantic and unique, but still instantly recognizable.
10. Game of Thrones Queens (Pick Your Fighter)
If you’re a brunette with long hair, you’ve basically got your pick of the Game of Thrones ladies.
- Cersei Lannister (early seasons): Loose waves, regal gown, and that “don’t cross me” glare.
- Melisandre: Red gown, smoky makeup, and mysterious energy.
- Arya Stark (grown-up version): Edgy warrior outfit with long brunette locks tucked back.
Ever wanted to rule Halloween like you’re claiming the Iron Throne? Yeah, this is your move.
11. Vampire Queen
Dark hair and vampire vibes go together like candy and cavities. With your natural brunette locks, you can slay (pun intended) a vampire look without much effort.
- Curl your hair or keep it straight and sleek.
- Dramatic eyeliner and red lipstick.
- Add fake fangs and a cape.
The great thing about a vampire costume? You can make it classy, gory, or sexy. Either way, your long hair will add that mysterious, seductive edge.
12. Pop Culture Icons (Cher, Kim K, Megan Fox)
Sometimes the best Halloween costume is just leaning into pop culture icons known for their brunette bombshell hair.
- Cher (’70s): Long, center-parted, boho glam.
- Kim Kardashian: Bodycon dress, sleek ponytail, contour that could cut glass.
- Megan Fox (Jennifer’s Body): Cheerleader uniform with sultry waves.
These work especially well if you want people to say, “OMG, you nailed it” without having to explain your costume 17 times.
