There is a clash among the definitions of prudery, modesty and lewdness. Years ago one of our ladies had parked on the top floor of the Raleigh Springs Mall garage. As she left the store, she saw only one other car up there. As she advanced toward her car, this man got out - wearing only his shoes and sunglasses.
What a clash of ideas! The flasher's actions are defined (properly) as indecent and illegal. Yet females can expose the major portion of their secondary sex organs and that is accepted as fashionable.
