Not a bad idea.  In fact, a very good idea I had failed to capitalize on.  I've seen some Harley Quinn cosplay in real life where the female had an attractive figure but the make up job was so horrendous that it ruined the mood.  But what we have here is one of the better ones.  Let's see if I can dig up soon of the good ones myself.

Asuka Kazama from Tekken

Miku and Friends.

Dixie from Rumble Roses.

I once had this as my avatar here on VGChartz and was moderated for it.

Inspired by the Harley Quinn cosplay posted by Angelus and after discussion with him, here are more pics from that same image set.
