Stumbled across a fantastic 1880 photo of a woman in jester-styled fancy dress [link] and could not for the life of me resist designing something similar for Harley.
So lovely, really like the retro style you used here .. it fits Harley quite well, personally i was surprised when becasue of the fact it took me so much time to realize that Harley Quinn's name is actually a play on 'Harlequin' .. which means 'female jester' .. maybe becasue English isn't my first language things like this slip by me easily XD
