28 Brunette Halloween Costume Ideas for Brown and Black Hair in 2023

Ashley Spinelli from Recess

Although we're pretty sure this is just Olivia Rodrigo on a normal day, she aced the Recess character's look between the the ribbed beanie, edgy jacket, and braids. Not to mention, you'll be comfy af!

Mabel Mora from Only Murders in the Building

Mabel is the fashion icon no one knew they needed. There are so many fits to choose from, including her fur coat, beanie, and over-the-ear headphones look from the first episode, or you can opt for this one from the first season's finale. Just add a BIG bloodstain if you'd rather be "Bloody Mabel." IYKYK.

Kim Kardashian

As someone who has a collection of memorable looks, it's kinda hard to top Kim's infamous "couch dress" from the 2013 Met Gala. Grab the most...interesting floral fabric you can get your hands on and make sure everything except your head is covered in it. Don't forget to add a baby bump.

Mia Thermopolis from The Princess Diaries

This Disney princess costume? Not so expected! Go as Mia before her makeover if you've got a school uniform hanging around, or go with the royal after version if you want to get all formal with your costume.

Olivia Rodrigo in "Sour Prom"

You already know you'll see more cheerleading uniforms and sticker-covered faces for Halloween (just like last year), so how about a little "Sour Prom" moment for an Olivia Rodrigo costume instead?

Queen Charlotte from Bridgerton

Sorrows and prayers for everyone else this Halloween when they realize there's no way that they can compete with your regency era costume. Grab your finest jewels and nicest clothes to be the true diamond of the season.

Wednesday Addams

When it comes to recreating Wednesday Addams's signature look, you need the three Bs: braids, black clothes, and brown/black hair.

Everything Everywhere All at Once

There are about a million outfits you could choose from EEAAO, corresponding to all the parallel universes we see, but how about the iconic duo of Michelle Yeoh and Jamie Lee Curtis in matching frumpy outfits and hot dog fingers??

Mighty Thor

Ok, so, if you wanna make a full metal breastplate, more power to ya. But pasting some metal pieces on a vest, getting a red cloak and hammer, and wearing your hair long will do just as nicely to channel Natalie Portman in Thor: Love and Thunder, tyvm.

Selena Quintanilla

An iconic look! Choose from one of Selena's many tour costumes (like this one from the Houston Astrodome) or award show outfits and pay tribute to the late singer.

Selina Meyer

Did Veep end in 2019? Yes, sure, but it's never been more relevant to quote some of her more iconic lines. Now that's staying power! (Also, all you need is a full-coverage work dress, a matching purse and shoe, and a fancy blowout.)

Isis from Bring It On

Say it with us now: "Brr! It's cold in here. There must be some Clovers in the atmosphere." Just sayin, the Clovers green cheer uniform is far superior to the Toros' (sorry bout it).

Wonder Woman

Who doesn't want to be Wonder Woman for a day? Transforming into this timeless superhero will never go out of style and can be portrayed in so many different ways—just don't forget the golden tiara, plz.

Billie Eilish

Nina Dobrev nailed this Billie Eilish costume. Sure, it's been a few years since "when the party's over" dropped, but the visuals of her crying black tears still lives rent free in our minds.

Daria

I know you already own a green jacket, tennis skirt, and combat boots—or something like it—so as long as you've got brown hair, too, your costume's basically set.

Emily Cooper from Emily in Paris

With season 4 in the works, channeling your inner Emily Cooper is the perfect way to prepare for the next chapter in Emily's whirlwind of a story. Pick your perfect blazer, heels, beret (duh), and don't be afraid to play around with patterns.

Jenna Rink from 13 Going on 30

This iconic dress is perfect to dance the night away in and show off those "Thriller" moves just like Jenna in the movie.

Maddy from Euphoria

Maddie is and will always be THAT girl. Whether you want to wear her two piece set from the carnival episode, rock her cheerleader outfit, or go looking for Nate at a house party in this all black number, just make sure you flex those makeup skills. Don't be afraid to add a ton of sparkle to make your eyes pop.

Rue from Euphoria

If you don't have the patience to apply all the individual crystals for a Maddy Perez costume, this under-eye glitter is much easier and just as recognizable.

Samara from The Ring

It's been nearly 20 years since this movie first came out, and to this day, if someone flips their brown hair in front of their face, your mind goes straight to this horror film.
