Twenty five years ago, I lived in San Francisco. This website was "talk of the town" for a quick minute. The real trick is looking at people's hair styles. In my experience, fashion indicates one's ethnicity/nationality much more than face shape alone. Think about a blond Italian from northern Italy, vs a blond German from southern Germany. They will have wildly different fashion styles (clothes and hair). The same for a Londoner and a Parisian.
