On any given Halloween night, you're likely to see a pretty good mix of people dressed as "sexy" nurses or cats (with the occasional mouse ). And given how popular Harley Quinn has been of late, it'd be pretty surprising if she wasn't among the most popular costumes this year.In fact, if Pornhub's insights are anything to go by, Harley might just beat out nurses as the most popular costume of 2016. According to data on Pornhub's most popular costume/cosplay searches, Harley Quinn is this year's "sexiest" Halloween costume. Sure, Suicide Squad wasn't every critic's favorite , but it seems to have triggered a surge in popularity for Harley Quinn-inspired porn.
