Do you think Joker and Harley Quinn costumes would be a cute couple halloween costume?

It all depends on where your going or who your going with. If your going to be with people that would know who Harley Quinn is the yes, its a great idea.However, Harley Quinn has been in alot of the comics but not the movies so not alot of people know who she is! In this case you'd better go as another couple such as Batman and Catwoman, Clark Kent and Lois Lain or Spiderman and Mary Jane. :)
