Let’s be real—picking a Halloween costume is basically an Olympic sport at this point. You want something original, Instagram-worthy, and comfortable enough to survive an entire night of candy raids, haunted houses, or whatever plans you’ve got.
Don’t stress—I’ve rounded up 12 trending Halloween costume ideas for teenage girls in 2025 that’ll make you the star of the night (and maybe even go viral). Ready? Let’s get spooky. 👻
1. AI-Influencer Inspired Costumes
Yep, you read that right. Thanks to the rise of AI influencers (looking at you, Lil Miquela wannabes), dressing like a futuristic, digital “It girl” is the thing.
- Think metallic mini dresses.
- Add neon wigs or holographic makeup.
- Accessorize with LED jewelry.
Why it works: It’s futuristic and current at the same time. Plus, everyone will get the joke when you say, “Sorry, I can’t blink. My software’s updating.”
2. Barbiecore 2.0
Barbie may have peaked in 2023, but the pink aesthetic isn’t dead—it just evolved. Barbiecore 2.0 in 2025 is all about mixing glam with a little rebellion.
- Hot pink blazers with edgy accessories.
- Chunky boots instead of heels.
- Think Barbie meets rock concert.
Personal tip: I tried a Barbiecore look last year, and honestly, it was the most comfortable I’ve felt in costume. Everyone recognized it instantly.
3. Wednesday Addams (But Updated)
Okay, Wednesday never really goes out of style, but in 2025, the trend is leaning toward “Modern Wednesday.”
- Black pleated skirts and chunky platform boots.
- Smokey eyeliner with glitter accents.
- Add a leather jacket for that rebellious twist.

Ever wondered why Wednesday works every year? Because it’s equal parts spooky, chic, and low-effort.
4. K-Pop Star Vibes
The K-Pop wave isn’t slowing down, and you can channel that energy for Halloween.
- Sequined outfits or bold stage looks.
- Glitter hair spray and rhinestone makeup.
- Add a fake headset mic for the full effect.
Why it’s genius: You can pick your fave idol and show off your inner superstar. Bonus—you can literally break out into choreo mid-party.
5. Viral Meme Characters
Who doesn’t love a good meme costume? 2025 is all about living memes—basically, if it trended on TikTok, you can wear it.
Examples:
- The “NPC livestream” character (yep, the one who says “Ice cream, so good”).
- The distracted boyfriend meme—updated with Gen Z flair.
- The viral tomato girl aesthetic.
IMO: These costumes are perfect if you want laughs more than scares.
6. Cottagecore Witch
Picture this: a cozy forest witch who bakes bread, grows herbs, and hexes toxic exes. That’s the cottagecore witch aesthetic trending hard right now.
- Flowing dresses in earthy tones.
- Flower crowns mixed with dark eyeliner.
- A basket of (fake) herbs or potions as props.
It’s spooky meets soft girl—and it works like magic. ✨
7. Cyberpunk Warrior
If you’ve ever thought, “What if Halloween, but with Blade Runner vibes?”—this is your sign.
- Neon accents on all-black outfits.
- Futuristic makeup with metallic streaks.
- Fake LED swords or toy blasters.
Pro tip: I rocked this look at a comic con last year, and it turned heads everywhere. Plus, it’s basically a reason to wear combat boots guilt-free.
8. Fairytale Villains Reimagined
Forget being a princess—2025 is all about villain energy.
Options:
- Evil Queen with a glam, modern gown.
- Dark Little Red Riding Hood (think leather cape).
- Maleficent-inspired horns but with rhinestones.
Why be the hero when villains clearly have more fun? ;)
9. Y2K Nostalgia
Yes, Y2K is still alive and thriving. For Halloween, lean into it harder than ever.
- Low-rise jeans (if you dare).
- Sparkly crop tops or butterfly clips.
- Think Paris Hilton meets early Britney.
FYI: You’ll need confidence for this one, but that’s half the fun.
10. Anime Heroine
Anime-inspired costumes have exploded lately, and 2025 is packed with options.
Fan favorites include:
- Sailor Moon-inspired outfits with a twist.
- Chainsaw Man’s Power (fake weapon included).
- Any Studio Ghibli character—always iconic.
Bonus: Cosplay wigs are easier than ever to find online.
11. Retro Horror Icons
Classic horror is back, but 2025 puts a teen-girl spin on it.
- Glam Chucky (with glittery overalls).
- 80s slasher girl—but make it TikTok-ready.
- Ghostface… in a sparkly mini dress.
Why it slaps: You get the nostalgia factor plus the cool, modern twist.
12. Group Aesthetic Costumes
Let’s be real—Halloween is better with friends. Group themes are trending, and the cuter, the better.
Ideas:
- Different Taylor Swift eras.
- Zodiac signs (each person picks their star sign).
- “Inside Out” emotions with pastel outfits.
Personal fave: My squad did “Bratz dolls” once, and we got asked for photos all night. Group costumes just hit different.
Quick Tips for Rocking Your 2025 Halloween Costume
- Comfort is key. If you can’t sit, walk, or dance, it’s a no-go.
- Props make the look. A simple accessory can turn “meh” into “amazing.”
- Confidence sells it. Own it—even if your costume is literally a giant slice of pizza.
