To tell you the truth, the two sentences aren't the same to me.

"She was nude..." emphasizes her state of undress. "She stood there nude..." emphasizes the fact that she was standing, and the "there" suggests a kind of familiarity with her environment.

I don't know. I guess I haven't seen that much of this kind of thing for it to bother me. The passive voice I worry about are in things like "The whip was picked up by him" instead of "He picked up the whip."

Besides, what do you do with Dickens' "It was the worst of times; it was the best of times"?
