I have answered this a few times, and I'll be honest, I think the more complicated the writers get, the less it fits Power Girl's character. To me, it's Karen. She dresses the way she wants to and fuck anyone who tells her she shouldn't. :)
"I'm Power Girl, and I LIKE this costume. You think I give a &^%$ what you think about it?"
That's Karen, to me.
