Best: Catwoman (Batman 60s series)

Portrayed by: Julie Newmar, Eartha Kitt 

You never know what you're going to get when it comes to the 60s Batman series, and while Catwoman seems like a costume that'd be impossible to fuck up, the fact they didn't is still impressive. Julie Newmar and her successor Eartha Kitt put on for the cat burglar in a sultry way that would be emulated in every following iteration of the character.
