ok
i have only read the past 2 pp. of this thread, but
i'm italian and just moved to paris from london,
so i feel like commenting on this:
i think style isn't just a matter of clothes, it encompasses a way of living in general (food, cities, weather, daily routine).
in countries like france (or italy) this is very much based on 'quality', intended as making the best of what you already have, including your physical appearance, rather than wanting to change it.
maybe i'm wrong, but i feel that in london, or new york, pleople are more concerned about being hype than in most of europe, and tend to accumulate clothes, styles and even identities in relationship to trends. this doesn't happen in more tradition-based places.
having said so, i do thing that there's something special about french women's style, which i guess i could call 'sophistication', meaning making something simple become unique and glamourous, if i see what i mean.
i'm from rome, so not the most fashionable city in italy (which is undoubtely milan), but i think french women are more sophisticated than italian, because they tend to be less conformist.
