Naked
"I always say: To be well dressed, you must be well naked." --Oscar de la Renta There is something that comes over a woman when she choses nudes as one of her outfits in her session. There is a confidence that accompanies the taking off all of the clothing you use in so many ways to cover so much more than even just your body.
It's as if each of them shed their skin along with their clothing and they revel in the freedom of it. That, to me, is the epitome of sexy.
