Right from the start, Princess Kate was recognized for her smart fashion choices. Author Catherine Mayer recently released the book, Divide and Rule: Royal Women and Their Battles. An expert on royal women, Mayer speaks exclusively to Marie Claire about how Princess Kate's style choices will be remembered, and why she's so important. "But they are fashionable while also conveying that she is, as Princess of Wales, part of a historical continuum." In the same interview, the royal author notes that Princess Kate seems to be following in Queen Elizabeth II's footsteps, in some respects.
