So Anon., if we use your definition of the standard of "White" beauty - it would seem that only two of the top-ten qualify.
But even these two share the phenotypic trait of larger than average lips.
And Ms Kroes lacks the requisite Blond hair.
The thing that all of the women have in common is a certain amount of juiciness - not a bland, shapeless sylph among them. Again... why are the traits generally associated with white beauty lacking in the most beautiful "white" women.
