So, do you dig deep in your pocket for a few bucks, and tell the lovely lady to go buy something to cover up, or do you tell her she looks just spectacular the way she is and she should stay that way?
On second thought, offering to take her shopping, to dinner, and then to entertain her back at your place for the rest of the evening is what any self respecting gentleman should do. And isn't that how it usually works with women even if you don't find them begging naked on the street????
