Kate Middleton has managed to make it on top "Vanity Fair's Best Dressed List" for the third time. As she often incorporates various colors in her style now, there is no denying how ethereal she looks in cream and white.

The Duchess of Cambridge has caused the term, the "Kate Effect." It's dubbed from her unique and classic fashion style which is followed by a lot of women all over the world.

Having the world as her catwalk, it is essential that Kate looks her best each and every time she steps out in public or engages in her royal duties. So far, she has made herself more of a style icon and has rarely failed in impressing her critics.

Even before she was given the title of Duchess of Cambridge and after she appeared at the Royal Wedding in a celestial Alexander McQueen wedding gown, she has made her mark in the fashion world.

Although blue is her more preferred hue to wear, it is undeniable how divine she looks in cream and white. From the same fashion brand Alexander McQueen and other favorites such as Jenny Packham and Alice Temperley, Kate Middleton looks fresh in such clean hues.

As she graces the cover of "Vanity Fair," America's leading society magazine in September as the world's best dressed, see more of the Duchess of Cambridge as she slips in delicate creams and whites.
