Psychology is also at work when you look at the women of Paris. The principle at work here is the assumption of style and the amplification of grace. Because you are in Paris, you assume that women are fashion-aware, which colors all your judgments about dress, hairstyle, and other factors of appearance. Because you suppose the most stylish of intentions behind whatever the actual outcome, you will find seductive and ennobling qualities behind almost everything and anyone. What would be a dowdy old hag or a trampy termagant in the wrong part of Baltimore is suddenly the epitome of French cuteness. It’s a sophisticated variant on the “Emperor without cloths” syndrome.
