1. Joker and Harley Quinn
Suicide Squad. Joker. Harley Quinn. Jared Leto. Margot Robbie (we at The Top 10 like Margot Robbie)! From the summer blockbuster hit we get everyone’s favorite, and most dysfunctional, couple. Las Vegas odds have it at 2 to 1 that you will run into AT LEAST five couples dressed as the Joker and Harley Quinn, that’s per each Halloween event.
