Standing fully naked in front of a with big picture window. For added plausible deniability, choose a room with a view, like a river view or overlooking some landmark in the city. This is open to all kind of variations, like sitting on a chair with open legs, or drying herself after a shower, better if with a leg propped on a chair for a full pussy view. Bottomless on a hotel balcony also works great. All spoken from experience.
