Listening to Scott on K's podcast and he said the art vision is based upon something like steampunk (forgot the name) where people envision what the future looks like from an 80's lens. In effect, you pretend that you are living in the 80's and imagining what the future looks like. It makes sense as part of the story you are being sent to the 80's to blow up the reactors, so to blend in you would have to imagine the clothes being worn, etc.
Listening to this I am understanding better Scott's vision. Although not initially a fan of the girl's attire in particular, I am going to reserve judgment until the full package comes out now that I understand more of the vision. Regardless, kudos to Scott for the kickass job he has done to bring this to fruition!
