Bar Swagger

So what's the proper bar etiquette? I've only been to one bar and that was in Tacoma in Washington and that sasuage fest was anything but the fancy smancy chic bars you see on TV shows. If a lady wanted to land a man or even a quickie, how should she approach this kind of a bar? Should she wear a tight fitting tshirt and jeans? Only if she wants to get knocked over the head and dragged by her hair back to his cave. Should she wear a chic evening dress? Only if she wants to get mugged and gang raped, but then again that may not be all that bad since she did wanted some action. So how should she dress? Easy, like this...
