22nd June 2010: Reffrence Found After watching some clips of Batman: the Animated Series, i've found some better reference images which show something closer to the look i'm going for.
In particular this video was helpful;

It's also got plenty of good reference for Mark Hamill's various laughs he did for the Joker.
30th March 2010: Inital Thoughts Well i bought a purple waistcoat and cravat for part of a costume for a friend's Victorian themed birthday outing. I purchased purple specificity so it could double up for this costume.
I'm currently hoping to do this for the October Expo; and see if i can get a DC Villains group going.
