This year, you can expect plenty of Justin Bieber and Hailey Baldwin costumes, but if you're thinking of going as Baldwin, there's one important question to answer: Are you blonde enough to pull it off? Because in order to do the leggy model justice — and so many other pop culture icons, for that matter — you have to get one thing right: the hair.
So, to make your life a little easier, we recommend starting your costume from the top down. Whether you're planning to buy a wig or just styling your own hair, we have all your Halloween hair inspiration ahead. These looks range from a Cher's waist-length black hair to a platinum Xtina with colored streaks, but each one is a Halloween classic.
Cher
Cher's look is all about jet-black, pin-straight hair parted right down the middle. Hairstylist Harry Josh let us in on the secret to Cher's iconic hairstyle: an ironing board. "She used to actually iron her hair on an ironing board to get it that straight and smooth," Josh told us. Now, we have flat irons, but you get the gist.Photo: Michael Ochs Archives/Getty Images.
Madonna
It's impossible not to have a bomb Halloween night when you're channeling the best of the '80s punk via Madonna. You'll need a big tulle hair bow, wax texture spray, sparkly eyeshadow, an oversized denim trucker jacket (worn backwards, of course), and every piece of chunky jewelry you own.Photo: Michael Putland/Getty Images.
Donna Summer

Marilyn Monroe
To really pay homage to Monroe's coiffed blonde hairstyle, you'll probably need a wig. Or, if you already have the color, you can take a cue from Lady Gaga and grab the Velcro rollers to recreate the curly bob. Either way, a red lipstick is a must.Photo: Bettmann/Getty Images.
Janet Jackson
Name a more iconic box braid hairstyle than Janet Jackson's high pony in Poetic Justice... we'll wait. Don't forget to stock up on headbands and hats to accessorize the look.Photo: KMazur/WireImage.
Jackie O.
Jackie Kennedy Onassis invested time into her hair. To get that signature bouffant, you could run to your local Drybar with this White House photo for inspiration. Or, opt for an at-home blowout. After you add volume with a round brush, make sure you have have some hot rollers on hand to help with perfecting those curled-under ends.Photo: Bettmann/Getty Images.
Audrey Hepburn
With a high ballerina bun and a teeny tiara, you can easily recreate this Breakfast at Tiffany's look. Bonus points if you already have wispy baby bangs.Photo: Bettmann/Getty Images.
Tina Turner
If you're going to an '80s party, Tina Turner's shag hairstyle is the perfect look. To get in the mood, jam out to "What’s Love Got To Do With It" on repeat as you tease your hair (or wig) to the max.Photo: Francis Apesteguy/Getty Images.
Christina Aguilera
A hair icon of the early 2000s, Christina Aguilera made us beg our moms for a crimper and colored hair extensions. And if this inspiration isn't doing it for you, look back at how Kylie Jenner styled Xtina circa Halloween 2016.Photo: Jeff Kravitz/FilmMagic.
Sade
The signature Sade look consists of a slicked-back rope braid, gold hoops, and a turtleneck. Some things are timeless for a reason. To recreate her hair for Halloween, stop in at the beauty supply store to get a faux pony.Photo: Dave Hogan/Hulton Archive/Getty Images.
Jane Birkin
Just got new face-framing fringe? Then, you won't have to do much to pay homage to one of fashion's finest. Obviously, bangs are a must for this one. High-waisted jeans are also strongly encouraged.Photo: REPORTERS ASSOCIES/Gamma-Keystone/Getty Images.
Selena
On stage, Selena Quintanilla typically left her long black hair down, but she's often memorialized by her red-carpet appearance at the '94 Grammy Awards (after winning for Best Mexican/Mexican-American Album). There she sported a stunning updo with piece-y curls framing her face and her signature red lip, of course.Photo: Vinnie Zuffante/Getty Images.
Twiggy
Before Victoria Beckham came along, Twiggy was the classic "it" girl. If your hair is blonde and short, this look is totally doable with a little styling mousse, a side part, and mascara dotted across your lower lash line.Photo: Michael Ochs Archives/Getty Images.
Diana Ross
Known as the Queen of Motown, Diana Ross rocked many different hair looks that you can mimic. The only requirement: The hair must be big. Everyone — from Yara Shahidi to Rihanna — is wearing big curls inspired by the music icon, but none can touch the fabulous, high-glam that Ross made famous. For this look, you'll need an Afro pick and a mic to carry around.Photo: Harry Langdon/Getty Images.
Beyoncé
Though most Beyoncé costumes involve stilettos and a black leotard, we're partial to On The Run II Bey — simply because this braid is epic.
Ariana Grande
No Ariana Grande costume is complete without a high-and-tight ponytail spilling down the front of your oversized sweatshirt.
