it's kind of hard to say which country has the most beautiful women. USA would probably have the greatest number of them, but i think the Nordic countries (Norway, Sweden, Denmark, Finland and Iceland) have a larger prosentage of beautiful women.
I live in Norway and I hear regularly that there are so many beautiful women here, "everywhere you turn theres an attractive woman" is a phase I've heard lots of times from visitors.
personally i like Swedes, but it's a language thing, nothing turns me on more than a dirty talking Swede
