Not in my experience. Paris does have some fashion plates types, as do most large cities, but average and poor dressers abound. If you don't want to look like a tourist simply don't wear shorts, a polo shirt, and don't have a camera constantly draped around your neck. On the other hand, who cares if you look like a tourist? That being said, I simply dressed as I usually do while in Paris. Jacket and tie for dinner, comfortable clothes for walking around.
