Valerie Plame is far more lovely than Paris Hilton. And while Paris gratuitously shows off her body, Plame just dresses normally and attractively. What a difference!
That, rather than any sort of demure behavior and conservative dress is most likely the point of her attraction for you.
Paris, to her credit, is heir to a billion dollars (and I doubt she waits for the third date).
