2023 Costume Ideas
Barbie is definitely one of the biggest movies of 2023, and a huge source of fashion inspiration for us all.
If you want a Halloween costume idea that’s cute, sexy, and most importantly, super on-trend for 2023, we highly recommend dressing up as Barbie this year.
For a classic Barbie doll look, the most important thing is to think pink!
On top, wear a cropped t-shirt or tank top that features the iconic Barbie logo.
On the bottom, nothing screams “Barbie” like a hot pink mini skirt.
If you want to stay true to the Barbie movie, you can also take inspiration from Margot Robbie’s incredible outfits, like cowgirl Barbie, ‘80s roller skate Barbie, or disco Barbie.
2. Pamela Anderson
Last year, the Hulu series Tom and Pammy starring Sebastian Stan as Tommy Lee and Lily James as Pamela Anderson took the world by storm.
This year, Pamela Anderson herself kept the momentum going with her Netflix documentary Pamela, a Love Story.
Take inspiration from this Pamela Anderson renaissance with a Pammy-inspired Halloween costume!
If you don’t already have Pamela’s gorgeous bleach blonde hair, sport a blonde wig, teased and hairsprayed into her signature voluminous ‘90s blowout.
Then, combine the iconic blonde hairdo with a provocative black leather corset.
If you want to take the look all the way, you can even apply a temporary barbed wire tattoo around your upper arm, or, if you’re artistic, draw it on with waterproof liquid eyeliner!
3. Wednesday Addams
Netflix’s hit series Wednesday may have come out in 2022, but because it was released after Halloween of 2022, no one has gotten the chance to recreate Jenna Ortega’s iconic costume for Halloween yet!
Of course, one of the most important aspects of a Wednesday Addams costume is her two long, black pigtail braids.
If you have long, black hair already, this is an easy girl Halloween costume. If not, you can totally buy a pre-styled Wednesday Addams wig!
Then, pair the look with a black mini dress. Make sure the dress has Wednesday’s signature white collar!
If you want your costume to be super show-accurate, you can also buy a recreation of Wednesday’s iconic sheer black school dance dress online.
Euphoria is another of the hottest, most fashionable, and most aesthetically pleasing TV shows out right now.
If you’re a fan of the show, you already know that it offers no shortage of incredible fashion inspiration.
Basically every outfit on Euphoria is worthy of a Halloween costume recreation, but one of the most iconic looks is Maddy’s New Year’s Eve party dress from the first episode of Season Two.
Her black bodycon dress with cutouts is sleek and simple, but also super sexy and instantly recognizable.
Don’t forget to do your makeup to match! No Maddy look is complete without her signature sharp black cat eye.
5. Taylor Swift
If you’re a big fan of Taylor Swift, you know that the Eras Tour is one of the most iconic pop culture moments of 2023.
At each tour date, Taylor Swift megafans are showing up to her concerts decked out in their best recreations of iconic Taylor Swift looks.
If you’re a huge fan of Folklore, we’re willing to bet that “Mirrorball” is one of your favorite songs from the album.
To emulate “Mirrorball” vibes, show up to your next Halloween party decked head-to-toe in silver glitter.
Pair a glittery silver top with a silver skirt for a look that’ll make you the shining star of any Halloween party. For more TS costume ideas, check out our full list of Taylor Swift halloween costumes.
Classic Costume Ideas
If you’re looking for a more classic and timeless Halloween costume, you can’t go wrong with a good ol’ cowgirl!
This costume is instantly recognizable, and better yet, is super easy to recreate with clothing items you probably already have in your closet!
Of course, no cowgirl costume is complete without a pair of cut-off jean shorts and a flannel or Western shirt.
All you need to do to finish off the look is get your hands on a cowboy hat and a pair of cowboy boots!
Another easy and classic Halloween costume for college girls is the idea of a lifeguard.
This costume is also easy to recreate with clothing items that you may already own.
If you have a pair of red athletic shorts, those are the perfect bottoms for a lifeguard costume.
On top, you can buy a tank top that says “lifeguard” on it. Or, if you have a red or white one-piece bathing suit, that’ll totally work, too!
Finally, accessorize the costume with flip flops, a red or white visor, and a lifeguard whistle!
Plus, if you combine this costume idea with our previous Pamela Anderson costume idea, you can create a super cute Baywatch-era Pamela costume!
8. Playboy Bunny
If you’re in the market for a super sexy, provocative Halloween costume, Playboy Bunny is probably the most classic sexy costume of all time!
Playboy Bunnies are waitresses who work at the legendary Playboy Mansion, and they’re famous worldwide for their iconic outfit.
To recreate the Playboy Bunny look, you’re going to need a corset, sheer black tights, and heels.
Then, of course, you finish off the look with a pair of bunny ears and a round little cotton ball to wear as a tail!
If you’re not feeling super creative this year and are looking for a classic, tried and true Halloween costume, you can’t go wrong with a witch Halloween costume!
This costume is also super easy to recreate with clothing items that you already own.
Most of the components of a sexy witch costume are super versatile.
Basically, you just need to bust out your cutest black dress, or alternatively, a black top and skirt.
The only thing you really need to buy is a big black witch hat, and you’re good to go!
10. Black Cat
Finally, if you’re looking for a cute, easy, and simple Halloween costume, but going as a witch isn’t really your style, try dressing up as a black cat!
Cat costumes get a bad rap for being basic and boring, but we think they’re a classic for a reason!
Like the witch costume, the basics of a cat costume are super simple. Just pick out a cute all-black outfit made of clothing items you already own!
Then, all you need to buy is a pair of black cat ears.
Don’t forget to draw on a cat nose and whiskers with some black eyeliner to really commit to the look!
Group Costume Ideas
11. Powerpuff Girls
If you’re going out as a group of three, you can’t go wrong with a classic Powerpuff Girls group Halloween costume!
This costume idea is especially fun because you get to delegate the Blossom, Bubbles, and Buttercup roles to match the personalities of the people in your friend group!
You can totally DIY a Powerpuff Girls costume using clothing you already own. Just create three monochromatic outfits in green, pink, and baby blue!
Or, if you don’t have the right colored clothing, you can also buy Powerpuff Girls costumes online!
Finally, the Powerpuff Girls’ blonde pigtails, red ponytail, and black bob are a super important part of their look.
If your natural hair doesn’t match up with your chosen character, you can also buy Powerpuff Girls wigs online!
12. Victoria’s Secret Angels
Another great sexy Halloween group costume idea is the iconic Victoria’s Secret Angels.
Although the annual Victoria’s Secret Fashion Show doesn’t happen anymore, the Angels are still an indisputably iconic part of pop culture history.
This costume idea is especially versatile because you can recreate it no matter how many people are in your friend group.
To dress up as a Victoria’s Secret Angel, all you need is a silky pink robe, some cute lingerie, and a pair of fluffy white angel wings.
13. Mean Girls
Mean Girls is another icon of pop culture history. For a super cute, instantly recognizable group costume, try dressing up as the Plastics!
If you’re a group of three, try dressing up in costumes inspired by Regina, Gretchen, and Karen’s iconic pink outfits from the Mean Girls poster.
If you’re a group of four, another really fun idea is to dress up in Regina, Gretchen, Karen, and Cady’s sexy Santa outfits from the Winter Talent Show.
Finally, if there are even more people in your friend group, you can dress them up as additional characters from the movie, like Damian, Janis, and Regina’s mom.
14. Austin Powers Fembots
Another really fun movie costume idea is the Fembots from Austin Powers.
This costume is a great idea for anyone looking for a fun, flirty, retro-inspired costume that accommodates groups of any size.
To recreate this look, you’ll need a baby pink teddy-style lingerie dress, pink opera gloves, and a pair of pink heels.
Then, to finish it all off, you’ll need to spray your hair into that requisite retro bouffant hairstyle!
15. Spice Girls
Finally, if you’re looking for a sexy college Halloween costume that’ll work for a group of five, you can’t go wrong with the Spice Girls!
The ‘90s are back in a huge way, and this group costume is the perfect blend of iconic and nostalgic.
Like the Powerpuff Girls costume, a Spice Girls group costume is an extra-fun idea because each girl in the group gets to pick the Spice Girl whose personality best matches their own.
If you’re dressing up as Baby Spice or Posh Spice, you might already have their signature baby pink and black minidresses in your closet.
But, if you’re dressing up as Ginger Spice, you might have to look online to find her iconic sequined Union Jack flag dress and red and blonde wig.
Couples Costume Ideas
16. Britney and Justin
If you’re super into the throwback, Y2K aesthetic and are looking for the perfect couples costume that fits the vibe, look no further than Britney and Justin.
This costume emulates Britney Spears and Justin Timberlake’s iconic matching Canadian tuxedos from the 2001 VMA Awards red carpet.
Nothing screams early 2000s like this look! Plus, it’s super easy to recreate with items you already have.
All you need is a denim dress or a cute denim top and skirt.
For him, all he needs is a denim jacket and jeans. Bonus points if he sports Justin’s iconic denim cowboy hat, too!
17. Sandy and Danny
If you’re into retro couples costumes, but you’re looking to throw it back a little earlier than the early 2000s, try a Sandy and Danny costume from Grease!
This costume is simple, instantly recognizable, and sexy.
All you need is a tight, off-the-shoulder black top, a pair of black leather pants, black boots, and some red lipstick.
His portion of the costume is even easier to recreate, all he needs is a black t-shirt and black jeans!
18. Cheerleader and Football Player
Finally, if dressing up as characters from a movie or pop culture isn’t your style, you can’t go wrong with a classic cheerleader and football player Halloween costume.
This costume idea is super cute, and as an added bonus, it gives you the opportunity to sprinkle a little school spirit into your Halloween festivities.
If you can, try to find a cheerleader outfit and football player outfit that match your school’s colors!
Halloween is one of the only times of year where you can let your creativity shine and go wild with your outfit. College Halloween parties are the best place to let loose, have fun, and most importantly, wow your friends with a super cute costume!
