Transform into Gotham's wild and cunning supervillain with our cool collection of Harley Quinn costumes for adults and kids. Harley Quinn is one of Gotham City's most devious characters. She first appeared in DC Comics Batman series in the 90's and has featured in DC Universe comics, movies and video games ever since. She may appear charming and cheeky at first, but she has a wild side that she’s not afraid to unleash! Dress up in the latest movie-look with our movie inspired Harley Quinn Outfit, head back to the 90's and don the original character look with our Classic Harley Quinn Costume or create your own costume with a signature Harley jacket, wig, stockings. Combine the accessories with a mock mallet or signature baseball bat and you’ll be instantly recognisable as the Gotham villain. We have Harley Quinn costumes for kids to enjoy too. Treat your little girl to one of our classic Harley Quinn fancy dress outfits for Halloween or for Comic Con. She's a temptingly tenacious character to portray and you'll have just as much fun picking out your costume.
