Hmmm.
I work with lots of French people and they're not good looking or stylish at all. I don't mean to be offensive, but I think you see it from an American point of view. Maybe the idea that French women are glamorous is pretty big in the USA, but here in Europe, esp in Britland, we don't see them like that. I mean, in the UK they get called "froggies", surely it's not a compliment
I am Italian, my bf is Scottish. I know for sure he's REALLY into the way I look (very mediterranean), YET I am very jealous of his exes, who were probably completely different from me. I dunno, you probably need to work on your jealousy full stop, without worrying about nationalities.
