Harley Qwednesday :: I Love Nerds
The following video isn't Harley Quinn specific but it does include a couple great Harley Quinn cosplayers and the cutest Harley Quinn WIN at the end, so I thought it more than adequate for a Harley Qwednesday post.
It is also a beautiful representation of the art of Cosplay and the world of nerds in general of which I am proud to be a member (not of the cosplay part, but the nerd part for sure.)
Keep on rocking you beautiful geeks!
