Best Costumes for People with Blue Hair

If you already have blue hair, you’ve basically won the costume lottery. While other people are panicking over whether to order a last-minute wig online or attempt a questionable DIY dye job, you’ve got a head start. Blue hair is a pretty bold choice for everyday life, but it’s also a golden ticket to some of the best characters around. Got a light sky blue? Maybe a dark navy blue color or electric neon? Don’t worry. There’s a character for you just waiting. From beloved anime heroes to nostalgic cartoon icons and even some simple ideas like the humble Crayola Crayon, we’ve rounded up some of the best costume options for anyone with blue hair.

Anime Characters

Listen, if anyone understands colorful hair, it’s anime. Anime practically wrote the rulebook on different hair color and blue hair inevitably finds it’s way into just about every series. If you have short, or sleek and shiny, then there’s a character already has a look tailor made for you.

Sailor Mercury made her name as the brainy one in Sailor Moon, but she’ll always be iconic in our book with her blazing blue cut. James, from Pokémon might on other end of the intelligence spectrum, but his lavender blue locks make him a good choice if you’re aiming for a goofy character.

And finally, we have Dragon Ball Z… which is sort of like the holy grail for blue haired cosplayers. Bulma’s hair makes quite a few changes through the seasons, but it’s often a shade of blue, and Future Trunk’s look switched straight to a blue middle-part cut in Dragon Ball Super. Of course, Goku and Vegeta traded their golden Saiyan hair for blue hair when tapping into their new God-mode powers.

Disney and Pixar Characters

Disney loves big personalities with colorful looks, and blue hair often means you’re either the life of the party or a little bit terrifying. Characters from Inside Out give you two extremes: you can embrace the upbeat energy of Joy or lean into the cozy gloom of Sadness. Joy’s sparkly yellow dress makes your hair pop with bright cheer, while Sadness’s chunky sweater and round glasses let you sigh dramatically all evening without anyone asking if you’re “okay.”

If your hair is darker or brighter, Hades from Hercules is an unbeatable choice. His sarcastic banter and fiery personality make him one of Disney’s most fun villains, and your hair already carries his signature look. Toss on a toga and smolder a little—you’ll have the underworld cheering.

On the cuddlier side of things, blue hair works perfectly for Sulley from Monsters, Inc. A fuzzy suit, some purple spots, and maybe a stuffed Boo doll complete the look. If you’d rather aim for something more current, Bluey is a brilliant choice. As the cheerful Australian pup, you’ll get instant smiles from kids and probably some knowing laughter from parents who’ve watched every episode fifty times.

Cartoon and Retro Characters

If you grew up on cartoons, you know blue was everywhere, especially in the ‘80s and ‘90s. That makes it a treasure trove of costume inspiration. The Smurfs are a simple but iconic option—blue skin, white pants, and a hat are all you need. Smurfette, Papa Smurf, or just “That Smurf,” your hair makes it authentic right away.

For something cozier, Grumpy Bear from Care Bears is a surprisingly fun choice. A comfy hoodie or pajama suit with a cloud-and-raindrop belly badge lets you lounge at the party while staying in character. Cookie Monster is another beloved blue legend. Stock up on chocolate chip cookies, and you’ll have a costume that doubles as a built-in snack strategy.

Marge Simpson, meanwhile, might be the queen of cartoon blue hair. Her tall beehive and strapless green dress are instantly recognizable. If your hair is already big or styled dramatically, you’re halfway to Springfield. And for those with spiky locks, Sonic the Hedgehog is a natural fit. Red sneakers, quick wit, and maybe a line or two about chili dogs bring the character to life.

Fantasy and Storybook Characters

Blue hair always feels a little bit magical, so it makes perfect sense to lean into fantasy and literature-inspired costumes. Mermaids are a classic option that show off your hair beautifully. Add a seashell top, shimmery skirt or tail, and some glitter, and you’ll look like you’ve just surfaced from under the sea.

Thing 1 and Thing 2 from Dr. Seuss are excellent for duos, especially if you know another blue-haired friend. Matching red jumpsuits and name patches are all it takes to become the mischievous pair that thrive on chaos. Coraline is another strong choice. Her short blue bob, yellow raincoat, and button-eye details make for a costume that’s both cute and slightly eerie, perfect for Halloween.

And then there’s the crayon. A simple, clever, and unexpectedly delightful costume idea is to go as a bright blue Crayola crayon. All you need is a monochrome outfit, some logo details, and maybe a pointed hat to mimic the tip. It’s playful, instantly recognizable, and a guaranteed conversation starter. Everyone loves crayons—so why not be the best color in the box?

Blue hair just makes most costumes better. You’ve already got a standout element that sets the tone. From anime icons, to a cartoon throwback, or something straight out of a storybook. So lean into it. Pick a costume that puts your hair front and center. Costumes are way more fun when it starts with what makes you unique.
