Actually, I read this thread, and its male counterpart, and have replied, thinking of statues. :-) Bodies as bodies. Movement is something else, and while obviously there's a feedback loop between long bones and joints on the one hand, and how that body moves on the other, I can easily separate the two.
Of course when we speak of the "perfect" form or beautifully proportioned dancers, one cannot think of them as statues, but how they move their bods.
I have heard that narrow hips are an advantage for elevation, a disadvantage for turnout.
