Do you ever notice that your little girl changes characters on the drop of a dime? We don’t know how it happens so fast. One minute a little girl will be a troll demanding a toll before you can get back to the couch and the next minute she’s perching on pillows and pretending to be a princess dolling out rulings to stuffed animals. Whether your little girl is into fairy tales or the family farm, she’s sure to love plenty of these costumes. From playtime to Halloween, dive into this category and you’ll find plenty of looks to make your child’s transformations smoother than ever.

Wearing costumes doesn’t have to be limited to Halloween. Themed birthday parties are always more fun than any other parties. Now, there’s the classic princess party of course. But you’re far from limited to that particular feel. For instance, you can have a zoo party. Have your birthday girl dress up as a zookeeper and everyone can dress as animals. We have all sorts of animal costumes from our frog, bunnies, kangaroos, and even an octopus! How much fun would that be!

You could even have a girls' superhero costumes themed party. Wonder Woman is the obvious choice, of course. But there’s also a variety of Batgirl and Supergirl costumes and an adorably smart Shuri costume. And let’s not forget the delightful villains. There are a lot of different Harley Quinn and Cat woman costumes.

Maybe your little one wants to dress up for a school event. Make that day at the science museum more interesting? Our dinosaur costumes will make touring through the fossils more picturesque than ever.  Speaking of educational costumes, there are plenty of looks that would work for historical events. For instance, perhaps your local community is hosting a fifties style sock hop. Or poodle skirt ensemble with make learning swing dancing unforgettable.

The decade celebrations don’t even stop with our variety of fifties costumes. Your little one can represent the peaceful protesters of the sixties with our hippie costume or represent the adventurous pioneers with our prairie girl costume or even our Annie Oakley costume. And that brings us to Renaissance Festivals. We have both medieval princess and peasant costumes that will make your child feel right at home in the historical setting. Is your little one a rebel? Show up at the Ren Fair with some pirate costumes. Those kings and queens better watch their coin purses.

There’s no limit to reasons why girls can dress up. There’s school, local festivals, and dress up at home. A healthy costume wardrobe is a recipe for an unforgettable sleepover. We’d love to see what kind of skit might happen when kids are dressing up as dinosaurs, mummies, and princesses at the same time. You just have to make sure that you get that on tape. A video of a princess sword fighting a t-rex could totally become viral! So, scroll through our amazing selection and find a couple of costumes for your little girl’s cast of characters. Because for some kids, the best type of toy will always be a costume!

Halloween Costumes for Girls

When it comes to playing dress-up, many little girls are experts from a young age. It honestly doesn’t take much to transport them to a magical kingdom or a lost tract of unexplored jungle. If you live with a little girl, you might walk in on a dozen different characters a week. If this playtime pastime is the norm in your household, investing in a Halloween costume for your creative kiddo means that the outfit won’t just be used that night, it’ll be used for months to come.

Talk to your little girl to find out which characters she’s enjoying the most lately. Is she feeling the fierce lion role? A high-quality jumpsuit will make for an awesome scene. Her favorite television characters, Disney princesses, or maybe even a dinosaur can make every playdate more adventurous and give you insight into what’s going on while she’s playing in another world.

Wonder Woman Costume Girl

If there’s one way to take down the monsters under the bed or put that scary window-scratchy ghoul in its place, it’s dressing as a superhero during playtime. When your little one dresses up as the iconic Wonder Woman, she’ll feel strong and unstoppable. You’ll love watching her march from house to house in the cape and crown while you’re out trick-or-treating. Check out the styles below to find the right costume for your kiddo!

Wonder Woman Costume for Teens

Wonder Woman Costume for Teens

Teen girl costumes can be tricky. Your kid’s almost grown. She’s going to want a look that shows how sophisticated she’s become. At the same time, deep down, she wants to have fun. That’s why Wonder Woman is a great option for your teenager’s upcoming Halloween event. While she might feel a little too old for trick-or-treating—or not, we still think about trying it every year—she might have parties, dances, and school-sponsored events. Top it off with a sword and she’ll have a look that’s posable and Snapchat worthy. This particular Wonder Woman costume will make her feel both fashionable and inspired for weeks to come!

Girl's Unicorn Costume

Girl's Unicorn Costume

Did you know that unicorns are natural dancers? Yeah, you might be surprised because pointe shoes aren’t exactly made for hooves. We think their dancing skills have something to do with their horn keeping them balanced as they spin and sashay. This being said, it totally makes sense to pick a unicorn costume with a tutu! You know your child will want to dance just like a unicorn as soon as she puts this costume on. Whether you’re headed to a parade, party, or trick-or-treating, this unicorn costume is comfortable enough to wear all day and fluffy enough to make your child count down the days until she can wear it.

This sparkly horse has pastel accents, shiny hooves, and a can-do attitude. In fact, it’s eager to deliver your child where ever they wish to go. All your kiddo needs to do is slip their legs through the unicorns’ legs, and it’ll look like they’re balancing on the beast’s back. The best part? If your child couldn’t decide between a princess and a unicorn, they can wear both! She can throw on her favorite crown and trot through the streets in this carry-on unicorn costume like the fairytale royalty you’ve always known she was.

Minions Unicorn Costume

And now your kid can be just as charming. Simply zip up the front of this adorable Fluffy costume and you’ll watch your child transform into this charming carnival prize.

Girl's Pirate Costumes

Searching the seven seas for good fortune, hiding treasure, and making friends with sea creatures will always be a grand adventure. And the best part? It’s easy to make these adventures come to life!

Girl's Brown Coat Pirate

A girl’s pirate costume means one thing: adventure! But a roguish look also has a fantastic side effect…it’s super photogenic. The costume featured here has a lovely ruffled skirt with a detail-oriented overcoat. It has a faux leather finish that pairs perfectly with the white ruffled skirt. Satin-textured leggings are layered underneath while the look is topped off with a jolly roger headscarf. All these details are important because when it comes to impressing the rest of your pirate cohorts, it’s all about a fantastic wardrobe! A fancy costume proves that a pirate knows what she’s doing when it comes to finding treasure. Ready for Halloween? Invest in a costume that inspires playtime adventures and makes for a fantastic photo op!

That little detail is not something we have to worry about when it comes to this particular pirate costume. This pirate dress is absolutely adorable with billowy silk sleeves and a fitted vest with gold trim. It’s belted around the middle and helps accent the poufy tulle skirt. The tulle drapes at the side, making your little one’s pirate jigs more adorable than ever.

Rebel Pirate Costume for Girls

Rebel Pirate Costume for Girls

For some little girls, this costume might be precisely what they have in mind when they ask to be a pirate for Halloween! They want something tough. Something that’ll let them escape from the stocks in a daring escape. They want an outfit that’ll let them snake down the cliffs of a hidden cove and into a rowboat to take back their ship under a moonless sky.

DC Superhero Girls Harley Quinn Costume

DC Superhero Girls Harley Quinn Costume

After almost 30 years of existence, it makes sense that Harley Quinn has been through a few stylistic phases. And while the jumpsuit is a lot of fun, Harley’s modern look is more reasonable for when she wants to roam the streets and drool over gems while planning an over-the-top robbery. Your child probably has specific ideas when she pictures Quinn. Ask her what’s on her mind and if she’s looking for cutoff jeans and pigtails, this modern Harley Quinn costume is sure to fit the bill!

Harley Quinn Tutu Costume

Harley Quinn Tutu Costume

Want to know a mischievous super villain secret? Everything is more fun in a tutu. This includes dancing as well as drop-kicks. If your daughter is dreaming of a playful Harley Quin ensemble, this one packs an especially awesome punch. With a simple fitted tank top and a fun fluffy skirt, your child will love wearing this costume so much that she might work it into her everyday wardrobe. Who can blame her? Rocking a Harley Quinn tutu is always a good time!

Harley Quinn Wig

Harley Quinn Wig

There are plenty of details that stand out when we’re thinking about Harley Quinn. One is her sharp wit, two is her love of checkered patterns, and three is her distinctive hairstyle. This Harley Quinn wig will instantly transform your child from a kid into a trouble-loving character. The red and blue stripe in the bright white shade of hair will stand out at any costumed event. When your kiddo is joining the bad side, they might as well go the whole way. ‘Cause doesn’t everyone want to be good at doing bad?

There’s nothing like a toddler dressed as a pumpkin trick-or-treating through the neighborhood to make people go “Awww”. Neighbors see these timeless looks and they think about when their kids were trick-or-treating or when they were the ones walking door to door. Whether your child wants to go all out or they’re just looking at this holiday as a chance to get fancy, this collection has options for kids with every interest.

Girl's Vampire Costume

Girl's Vampire Costume

If there’s any time of year to throw on some crimson lipstick and sneak into a room with your arms raised while growling about snacking on the blood of your nearest and dearest, it’s the Halloween season. Dramatic, dangerous, and mysterious, playing a vampire will always be a good time. We have plenty of vampire costumes for girls, but the costume featured here has all the classic vampiric fashion details that you might expect. A high web-patterned collar, a sheer batwing cape, and flared sleeves make this dress look like it’s straight out of an old movie. Pair this vampire dress with black and white makeup and some fake blood and your kiddo will be ready to take on their new nocturnal lifestyle.

Girl's Cat Costume

What are the most popular Halloween costumes for girls?

Certain costumes will always be popular. Are you looking for scary girl costumes? Witches have been a top Halloween pick for generations! Black cats and vampires will always be high on the list as well. Thinking about something trendier? Popular Halloween costumes for girls depend on what’s new in the theaters! If Guardians of the Galaxy is on the silver screen, there’s a strong chance that Gamora will be a top-selling costume that year. Is there a live-action princess movie coming to a theater near you? Then that princess’s look just might be your best bet. No matter what year it is, there’s one fact that’s evergreen. Whatever the most popular Halloween costume is, we’ll have it available at a reasonable price!

How do I pick out Halloween costumes for teen girls?

Teen girls are all unique…which is a super obvious statement but it’s true. Picking out an outfit for a teen as an adult is a daunting task. It’s best to search for a costume with your teen so you can discuss your budget and household rules. Guide your teen on their Halloween journey by talking about their favorite TV shows, hobbies, music videos, video games, movies, and YouTube channels. Watch them together, talk about them, and something is sure to stir up some ideas. Most of all, have fun with the search. After all, that’s what costumes are all about!

How to find Halloween Costume ideas for girls?

Want to know a secret? Cute Halloween costumes for girls are pretty easy to find. The trick is finding the right Halloween costume for your little girl. For instance, Halloween costume ideas for tween girls will be totally different from the costumes your Kindergartener would wear. Tweens might come up with their own ideas and you can work with them to get the look just right. Kiddos, on the other hand, need a little help or they might name the first thing they see when you ask them what they want to be. Then you have to figure out how to whip up a Tater Tot costume. Think about their favorite animals, movies, and books to come up with ideas. If your family reads Where the Wild Things Are over and over, a monster costume will be super adorable. And if Disney movies are a staple, all your little one has to do is choose a favorite character.
