Too bad! I, for one, love to get all dressed up for a nice, memorable dinner. It adds to the experience. I understand, in seeing much of my clientelle here in Paris, that the people who don't dress the part (to the extent of wearing jeans,etc) tend to be the wealthy ones , who do what they want, and don't give a crap about what others think. Ex: "If I can pay the bill, I wear what I damn well please" (I heard a client say once). Sad but true.
