Of the earth’s nations France is by far the one with the most class. They gave us Marie Antoinette and Louis XIV who have set the standard for all future classiness. In fact, if something is from France it is automatically classy. Cars, Wine, Bread, People, Diseases, anything!
But maybe the classiest thing about France is it’s language: French. There is no better way to show you are classy than by speaking it. If you cannot speak French, then knowing a few French words will go a long way: baguette, croissant, wine, sex are but a few! Memorize them and use them to be more romantic.
