^ I have a feeling the whole Manson package was a phase of experimentation. Being with someone as experienced as Manson probably made her feel really safe dressing the way she did. However you feel about Manson, he has been that way since he hit the scene and that confidence would probably be contagious for a young girl hoping to make a drastic change in her own life. He probably gave her the support she needed to step onto the stage feeling like she created the person standing before us.
I agree with you, though, she's naturally fair so the whole dark-hair pale-skin look is very unnerving and unnatural. Can't wait to see what she does after the alleged Broadway appearance!
