8 DIY Harley Quinn Halloween Costumes

Few fictional characters have gone through a style revolution quite as dramatic as Harley Quinn’s. First introduced during a 1992 episode of Batman: The Animated Series, the Joker’s girlfriend soon began to appear in comic books and video games, and as her character evolved, so did her trademark look. By the time Harley Quinn made her live-action cinematic debut in 2016’s Suicide Squad, she was one of the most popular anti-heroes in the DC Extended Universe… and Harley Quinn Halloween costumes have been everywhere ever since. And if you’re looking to wear a DIY Harley Quinn costume this year, then we have plenty of ideas to get you started.

Like many pop culture-inspired costumes, there isn’t just one way to dress up as Dr. Harleen Quinzel. Yes, you can recreate her ever-popular Suicide Squad ensemble, but we’ve got DIY costume ideas inspired by her comic, TV show, and video game appearances (as well as her other movie roles) that you can shop as well.

Dressing as Harley is the perfect Halloween costume for women who are heading out solo, but since she has so many different looks, you can easily find inspiration for a best friend ensemble or group getup. And, of course, if you have someone special in your life, then you can recruit them to dress up as the Joker for a fun couples costume.

Whether you’re hoping to put together an elaborate costume or something simple and last-minute, then there’s a Harley Quinn-inspired idea out there for you, and we’ve rounded up all the best.
