Every year brings a fresh wave of entertainment that captures the imagination of kids everywhere. From animated films and TV series to streaming hits and viral internet moments, pop culture plays a big role in shaping what kids want to wear when it’s time to dress up.
Whether it’s for a birthday party, Halloween, or school dress-up day, the right costume helps kids connect with their favourite stories and characters. Here’s a look at the top 10 pop culture-inspired costume trends for kids in 2025.
1. Bluey and Bingo
Bluey has been a household favourite for years, and it continues to dominate in 2025. With new episodes and global popularity, kids still can’t get enough of Bluey and her younger sister, Bingo. These costumes are easy to wear, bright, and super recognisable. They’re especially great for younger kids who want something soft, comfy, and full of personality.
2. Super Mario Bros.
Thanks to the ongoing success of the Super Mario Bros. movie series and popular Nintendo Switch games, Mario, Luigi, Princess Peach, and Bowser are as trendy as ever. These costumes appeal to both boys and girls, with lots of colour and fun accessories like hats and gloves. They’re also a hit with siblings or friends who want to go as a group.
3. Wednesday Addams
The Wednesday TV series on Netflix brought a new generation into the world of the Addams Family. Kids love Wednesday’s gothic style and smart personality, making her one of the top picks for dress-up in 2025. Her costume is simple—usually a black dress with a white collar and braided hair—but it stands out thanks to the character’s strong look and attitude.
4. Barbie and Ken
The Barbie movie in 2023 left a lasting impact, and its legacy continues into 2025. With new Barbie animated specials and themed merchandise, the classic doll has been reimagined in modern, fun ways. Barbie and Ken costumes can be sparkly, sporty, or stylish—depending on which version your child likes most. They’re bright, playful, and perfect for kids who love to dress up and perform.
5. Teenage Mutant Ninja Turtles
The Ninja Turtles are back in a big way, with a new animated series and rebooted movie keeping the heroes in a half shell at the top of the costume charts. Leonardo, Donatello, Michelangelo, and Raphael each have their own colour and weapon, making them great choices for group costumes or siblings.
6. Pokémon
With new Pokémon games and series continuing to launch, kids are falling in love with Pikachu, Eevee, and other iconic creatures all over again. Costumes for Pokémon trainers or the characters themselves remain hugely popular. They’re ideal for kids who enjoy adventure and want a bit of action in their dress-up day.
7. Mirabel from Encanto
Encanto may have come out a few years ago, but Mirabel’s colourful costume and heartfelt story keep her a top pick in 2025. Kids are drawn to her vibrant outfit, glasses, and unique personality. This costume works well for school dress-up events and Book Week costumes, especially when highlighting themes of family and self-discovery.
8. Spider-Verse Characters
Spider-Man continues to evolve with the success of the Spider-Verse animated films. Kids are now choosing from a wide range of Spider-characters—like Miles Morales, Spider-Gwen, and Spider-Man 2099. These suits are sleek, modern, and full of colour. They’re also a favourite among kids who want to dress as superheroes but still stand out from the crowd.
9. Percy Jackson
With the Disney+ adaptation of the Percy Jackson series gaining strong popularity, this Greek mythology-inspired trend is rising fast. Kids love dressing up as demigods with simple outfits like Camp Half-Blood t-shirts, fake swords, and sporty accessories. It’s one of the easiest costume ideas to put together and a perfect fit for Book Week costumes that tie directly to literature.
10. Wonka-Inspired Looks
With the latest film adaptation breathing new life into the Willy Wonka story, kids are excited about dressing up as characters from the Chocolate Factory. Bright jackets, top hats, and even Oompa Loompa costumes are trending again. These whimsical, colourful costumes let kids stand out and enjoy the magic of Roald Dahl’s timeless world.
Pop culture continues to shape how kids connect with the world around them. In 2025, the most popular costume trends blend storytelling, imagination, and vibrant characters that kids adore. Whether they want to dress as a ninja turtle, a demigod, or a cartoon dog, there are more options than ever for fun, affordable, and memorable outfits.
Best of all, many of these ideas work perfectly as Book Week costumes, helping parents get more use out of each outfit. As always, the best costume is one that makes your child feel confident, creative, and ready to play.
