Harley Quinn Costumes & Costume Ideas

Longtime fans of DC Comics remember Harley Quinn's first appearance on Batman: The Animated Series in 1992. Her wacky demeanor and memorable red and black harlequin outfit captivated viewers. When DC Comics revealed her backstory as psychologist-turned-supervillain, it added a depth to her relationship with The Joker that spawned a wildly devoted Harley fan base.

DC Comics changed her costume when they revealed the New 52 initiative in 2011, but many fans are devoted to her revamp in Suicide Squad, where she ditched the red and black in exchange for ultramodern outfits and eye-catching pigtails dipped in pink and blue.

Whether you'll team up with the Suicide Squad or get into classic comic mischief with Poison Ivy this Halloween, check out our favorite Harley Quinn costumes and accessories for kids and adults that you can use to create a truly unique outfit. Choose from Harley Quinn dresses, bodysuits, and more from her appearances in DC Comics, animated shows, video games, and films.

Cute & Classic Harley Quinn Costume

For the little mischief-maker who loves Harley Quinn's original DC Comics costume, this outfit is a must. The jester headband gives this ensemble the touch of playfulness it needs to ring true with her favorite harlequin baddie. It also features a pointed clown collar with pom-pom tips, black and red glovelettes with white ruffles, a simple black eye mask, and a cute harlequin dress. Halloween is the perfect night to play the part of a villain! With your lil' troublemaker decked out in this awesome officially licensed costume, kids and adults will know to watch out for hijinks. Group family costumes are easy with Harley Quinn as a theme. Pair her up with Poison Ivy, the Joker, or Batman!

Join the Suicide Squad!

Harley ditched that old jester jumpsuit for her new role in Suicide Squad. This new design meant a number of new fashion choices, but this outfit was by far her most memorable. The bomber jacket reads "Property of Joker" on the back, and comes attached to her "Daddy's Little Monster" shirt. Combine with the color block shorts and belt to look like you just walked off the set of the Suicide Squad sequel. For a final touch, throw your hair up in pig tails and grab a bat to really complete your Suicide Squad Harley Quinn cosplay costume. You'll be all ready to stir up some trouble with The Joker, Katana, Killer Croc, and the rest of the Suicide Squad.

Gamer Gear Harley Quinn Costume

Skip the dresses and get ready to take care of business in this bold Halloween costume inspired by Harley Quinn's character in the Batman: Arkham City video game. This darker take on Harley Quinn switches her usual red to maroon, turning away from the old clownish jumpsuit for a corset-inspired top and leggings printed with her iconic diamond pattern. Top it off with the choker, gloves, and belt, then style your hair in pigtails or pick up a Harley Quinn wig to finish the outfit. You'll look just like The Joker's psycho sidekick in Arkham City! This design is great for gamers and Harley Quinn fans alike, so lace up your boots and corset for a killer Halloween or cosplay costume.

A DC Comics Favorite

Take your Halloween costume back to 1992 with an old-school Harley Quinn outfit. In this red and black jumpsuit detailed with Harley's familiar diamond design, you'll look just like your favorite prankster in her debut on Batman: The Animated Series or from her first page in DC Comics. Small details like her jester collar, eye mask, and ruffled gloves make this more than your average Halloween costume. When you're all suited up, you'll be ready to help your main squeeze, The Joker, defeat Batman, or team up for double trouble with Poison Ivy. If you're still grieving the New 52, this Harley Quinn costume is the perfect choice for tried and true Harley fans at Halloween or a comic convention.

Kids Love DC Super Hero Girls!

If you have a fan of DC Superhero Girls in the family, you're probably familiar with this youthful take on Harley Quinn. In this reimagining, Harley isn't a power-hungry supervillain, just a bit of a class clown. She attends Super Hero High, and is actually friends with characters usually considered her greatest enemies! She's a bit unpredictable, but a lot of fun. For a creative kids' group Halloween costume idea, she and her friends can dress up as the DC Super Hero Girls, like Wonder Woman, Batgirl, Katana, and the rest of the crew. For extra fun, she can bring along a bag of tricks to show the other kids along with the usual Halloween treats, like whoopee cushions or a squirting flower!

Here Comes Trouble!

Sometimes it feels good to be bad. Play the part of the jokester we all love to hate with a cute Halloween costume that is sure to catch everyone's eye. If the red and black color combination wasn't enough, the iconic diamond design inspired by jesters and playing cards—another nod to Harley Quinn's sweetheart, The Joker—ensures that everyone at the party knows you're up to no good. Dressing up in a hero costume like Batgirl or Supergirl might be the more obvious choice, but playing the villain is much more fun! Embrace the crazy of DC Comics' queen of clowning, and cook up some trouble at your Halloween party! If asked trick or treat, Harley Quinn would choose the trick every time.
