Love the Westwood related smack down that went on some posts back. Friggn' unbelievable that some jerk could be like "A SUIT IS A SUIT." Oy. Knowing that cut makes a difference doesn't kill your heterosexuality.

Snazzy dressed dudes get babes, yo. The Westwood/Johnny influence is way obvious in the new outfit, which IS very different from prior incarnations. Check out the shape of a trench and compare it to tails--sigh.
Throwing my two cents in about the Harley costume:
While I LOVE the punkish-gothish-hottopic-ish look for Harley, as it is something I would wear, I'm a little bit hesitant to say that's how it should be... there's the whole psychiatrist thing, which would mean she was a professional and so on...
...but hey, I'm a psych major and I'm going to be wearing my stripey thigh highs on the weekends no matter what I do.
I think Harley SHOULD look a little ****ty... A ripped up, frazzled Harley with lots of ripped stockings, etc, I think would look perfectly fine next to TDK Joker...she's his sub, his doll--she'd be standing around in a daze looking vacant but hot, all sad that he told her to shut the hell up...then he'd snap his fingers or clap his hands and, BAM! she'd be animated again. Life would have meaning when he called her to.
I think I want a sliiight loli influence on the harley costume, just to give her the occasional old school style charm Joker has with the vest and pocket watch and all... keep the short shirt and the ripped layered stockings, but give her a snazzy waistcoat over a nice button down blouse. Or have her in a nice dress, just accessorized with weird stuff to give it that lovely thrown together look.
And rough up the make up some, of course.
It's sad that we'll probably never get to see a Nolan Harley (Oh, Heath! we miss you so!), because I think you could do an awesome story with a very, very gritty realistic Harley, playing up the abusive dyanmic between her and Mister J. Take away a lot of her silly "tee hee, puddin'!" stuff and you're left with a very, very effed up girl...lots of potential there. And you could do bursts of manic laughter but still be very serious.
Harley should not look like a dom. She belongs to Joker, 100%, and she knows it.
That said, thigh high boots do not equal dom in and of themselves.
