2 Samuel 11:2

And it came to pass in an evening tide that David arose from off his bed, after the noonday siesta, when the cool of the evening invited people outside, and walked upon the roof of the king's house, which was flat and parapeted, like all the houses of the Orient; and from the roof, which offered an all the wider view, since it was on Mount Zion, he saw a woman washing herself, taking a bath in the uncovered court of her house; and the woman was very beautiful to look upon. There is a warning here to every woman against in tent ional or unintentional exposure, whether at bathing-beaches, in street-dress, or about the house.
