These 16 Green Halloween Costume Ideas Are So Brat-Coded
2024’s biggest color trend has all the inspo you need ahead of Oct. 31.
It appears green is the new black. After a year of Challengers tennis-core, Charli XCX’s brat summer, and all the Wicked movie hype, it’s no surprise that emerald, mint, and jade hues are expected to be the main character this Halloween season.
Whether you’re planning an intricate outfit to wear to a party or throwing together a DIY look for that last-minute invite on Oct. 31, a green costume is clearly the way to go. Barbiecore pink may have been the it girl last year, but olive and lime are taking center stage in 2024 thanks to all the viral green moments of the past 365 days.
The iconic shade was spotted in new movies, music, and even at the meme-able Summer Olympics, but let’s not forget the TV and film characters who have been channeling green for years. These nostalgic choices like Tinker Bell from Peter Pan and Shego from Kim Possible can make head-turning Halloween costumes as well. All you need to do is think green to get started.
To spark some creativity for your ‘fit and inspire your vibrant color-coordinated look on All Hallows' Eve, here are 16 green costume ideas you can easily throw together for whatever Halloween plans you may have.
Charli XCX’s Brat Summer
Everything and everyone was brat this summer. From neon eyeshadow to green smoothies, brat summer took over and hasn’t really gone away. Thanks to Charli XCX’s remix album Brat and it’s completely different but also still brat and the Sweat Tour going string, the brat aesthetic is here to stay for brat autumn.
Channeling that lime green shade, dress as one of Charli XCX’s concert looks or the Brat album for Halloween. Just don’t forget the most crucial part, a stunning Brat-inspired makeup look.
Elphaba From Wicked
If the Stanley cup demand and seemingly endless Ulta makeup collabs didn’t already give it away, Wicked is about to be the biggest movie of 2024. Fans are already hyped online just from the trailer and teasers, so you’re sure to have a popular costume with something Wicked-inspired.
Since Elphaba is the moment, you might as well defy gravity, wearing all black, painting yourself green, and donning the iconic witch’s hat.
Slytherin Students From Harry Potter
Another magical green Halloween costume idea comes from the Wizarding World. Wear a black robe, green tie, and white collared shirt for a simple Slytherin student ‘fit.
To really sort yourself into Draco’s house, don’t forget your wand for Defense Against the Dark Arts class.
Clovers Cheerleader From Bring It On
Brr, it’s cold in here. There must be a Clovers costume idea in the atmosphere. This is such an easy ‘fit to throw together. All you need is a green cheerleader uniform similar to the one Gabrielle Union wore in Bring It On.
Disgust From Inside Out
Inside Out 2 has become the biggest animated movie of all time, so you’ll likely see a lot of Riley’s emotions on Halloween. The most demure of the Inside Out crew has to be Disgust. The green emotion is so cutesy with her dress, bob, and purple scarf.
An alternate green option from Inside Out 2 to consider is Envy, which Google lists as one of the top 10 Halloween costumes of 2024.
Peter Pan From Peter Pan
Another Disney character that’s known for wearing green is Peter Pan. Peter had a big year getting a name drop from Taylor Swift in her Tortured Poets Department song “Peter,” so this costume idea is also a great idea for Swifties looking for something unique. Just wear green tights, a collared shirt, and his hat with a red feather in it.
Tinker Bell From Peter Pan
A cute couple’s costume idea is to dress as Peter Pan and Tinker Bell. You just need a green dress, shoes with white pompoms, wings, and sparkling makeup that looks just like pixie dust.
Shego From Kim Possible
Throw it back to your Disney Channel days by dressing as Shego from Kim Possible. Dr. Drakken’s sidekick in black and green has become so popular on TikTok that #Shego is tagged in almost 72,000 videos.
For this look, dress in very Brat-coded green and black with her signature dark lips.
Poison Ivy From Batman & Robin
Shego may just be a sidekick, but if you want to channel full supervillain, you might want to go as Poison Ivy from Batman & Robin. The character made famous by Uma Thurman in the 1997 film is iconically green with gorgeous red hair.
To recreate this ensemble, wear a bodysuit with ivy details and a matching makeup look.
Buttercup From Powerpuff Girls
If you and your besties are as close as Serena, JaNa, and Leah from Love Island USA, plan a PPG group costume with your Powerpuff Girls.
Even if you don’t have a crew to dress up with, Buttercup is a great Halloween costume all on its own. Just throw on her green dress, white socks, and black ballet flats.
Princess Tiana From The Princess And The Frog
Who didn’t want to be a Disney Princess for Halloween as a kid? If you never got a chance, this is your year. With a green dress, you’re almost at perfect ‘fit status. Add some lily pad details, a crown, and green sparkles, and you’re good to go.
Zendaya From The Challengers Press Tour
Tashi Duncan is likely to be a popular Halloween costume this year, but it was Zendaya promoting Challengers that really turned heads with her incredibly themed looks. She took her method dressing to another level, so follow her lead with some tennis ball-inspired outfits for a winning look.
Shrek From Shrek
Everyone’s favorite green ogre has also had somewhat of a renaissance lately on the FYP — there are over 1.7 million #Shrek TikToks on the app. With Shrek 5 announced for 2026, it’s never too early to get a costume ready by going as Shrek this Halloween. A brown vest and a little green face paint — that’ll do, Donkey.
Raygun From The Paris Summer Olympics
From chocolate muffins to “pommel horse guy” (aka Stephen Nedoroscik), this year’s Olympics in Paris had so many memorable moments. However, the most baffling and green performance came from Australia’s Raygun. The breaker became an instant meme and perfect Halloween inspo.
The Green Team From The Disney Channel Games
Nick Jonas said the Disney Channel Games was like “Love Island on crack,” which confused Dylan Sprouse who had a very different experience than the JoBro.
Regardless, the DC Games were an iconic time for Disney kids, so a costume inspired by that nostalgia would be too cute. All you need is a pair of green shorts with a matching tee and accessories like a sweatband or baseball cap.
Winifred Sanderson From Hocus Pocus
Probably the most watched Halloween movie this time of year is Hocus Pocus. It’s a classic that never gets old. If the Sanderson sisters have put a spell on you, you might want to dress like Winifred in her green and purple dress. Glam it up with some witchy accessories, her spell book, and red pouty lips.
