Wearing a costume is a cornerstone of Halloween at any age, but things change as our kids get older. One year she wants to match her best friend, the next she wants something from a show you’ve never heard of, and the year after that she might say she’s “too old” for costumes (until the night of the party!).
Whether your daughter is trick-or-treating with friends, heading to a party, or handing out candy at home, here are 25 Halloween costumes for your tween or teen girl, from this year’s trending picks to the cozy classics.

What are the most popular Halloween costumes for teen girls in 2026?
This year’s trends come straight from what tweens and teens are watching and playing. Spirit Halloween’s 2026 trend list includes Toy Story characters, K-Pop Demon Hunters, superheroes, and Greek gods and warriors, and Google’s top costume searches include Princess Rosalina and Dolly Parton.
1. K-Pop Demon Hunters (Rumi, Mira, or Zoey)
The movie that took over every tween and teen playlist is still going strong. Start with Rumi’s long purple braid, then add a cropped jacket and lots of sparkle. It’s perfect for a group of three friends.
2. Greek Goddess
With The Odyssey in theaters this summer, Greek goddesses and warriors are everywhere. A white dress, a gold leaf headband, and a gold belt or cuff and she’s ready for Mount Olympus. It’s also an easy, comfortable costume that works for any age.
3. Jessie From Toy Story
Toy Story 5 brought our favorite yodeling cowgirl back. A red cowgirl hat, a cow-print vest, and a long braid make this one easy and fun, and it’s adorable with a friend as Woody or Buzz.
4. Princess Rosalina
Super Mario fans love this sparkly, star-covered princess. A teal gown, a silver crown, and a star wand and she’s ready to light up the night.
5. Dolly Parton
Big hair, big heart, and lots of fringe and rhinestones! Start with a big blonde curly wig, add a denim or sparkly jacket and a little country sparkle, and grandparents will love it.

6. One Piece Unicorn Animal Costume
Tween or teen girls can’t be more comfortable trick-or-treating in their PJs. This one-piece onesie unicorn costume is made of soft plush fleece and will add lots of fun to any Halloween party.
7. Angel Costume
You can get a halo and angel wings for her if she has a white dress! It’s one of the simplest, sweetest costumes there is.
8. Fairy Costume
One of my favorites, and the outfit and accessory options are endless! We love this one with a light-up skirt, wings, fairy wand, and headband.
9. Butterfly Costume
Let her spread her wings for Halloween with a butterfly wing cape. There are lots of colors to choose from.
10. Mermaid
A fancy sequin mermaid skirt for your girly girl! Add a seashell top or a simple tank and some glittery makeup.

A vintage-style vampire dress with a high collar, bell sleeves, and a cameo choker is elegant and just spooky enough.
What if she wants a costume I’m not comfortable with?
Costume season can bring up big feelings, especially with teen girls. Instead of a flat “no,” stay curious and work on it together. When she feels heard, she’s much more likely to meet you in the middle.
- With a tween: “I love that idea! Let’s look at a few versions together and pick the one that works for both of us.”
- With a teen: “I can tell you’re excited about this. Tell me what you love about it, and let’s figure out how to make it work for the party and for me.”
- When it’s still a no: “I hear you, and I’m not saying no to the idea. I’m saying no to this version. What could we add or change?”
Leggings, a jacket, a longer skirt, or a fun accessory can often solve the problem without a fight. What matters most is that she knows you’re on her team.
Halloween safety tips for tweens and teens
Halloween night is busier and darker than most. A study in JAMA Pediatrics found pedestrian deaths were about 43% higher on Halloween evening than on nearby evenings, and Safe Kids Worldwide reminds families to put phones away while walking and to cross at corners.
- Add reflective tape, a glow stick, or a small flashlight to dark costumes.
- Choose face paint over masks so she can see clearly.
- Agree on the route, the friends, and a check-in time before she leaves.
- Phones are for check-ins, not for scrolling while crossing the street.
- Make sure shoes are comfortable and costumes are short enough not to trip on.
