Robert, you question is impossible to answer because you have not provided any information about the mood you are trying to create. The subject you are shooting can be lit in so many ways, perhaps infinite. I do fine art nude photography and my lighting setups vary considerably.
You have said you don't want to see shadows, that requires very large aperture soft lights, perhaps powerful fixtures behind something as dense as unbleached muslin. I've used 12'x12' frames or even larger with a couple of 5Ks.
I suggest you view some films that have scenes that look like what you're trying to achieve and then light the same way. If you don't know how, you could ask a specific question, or read things like American Cinematographer.
