The Duchess of Cambridge landed atop Vanity Fair’s 2013 International Best-Dressed List for the fourth year in a row, sharing honors with Scandal‘s Kerry Washington. “The Kate Effect” remains in full swing as proven by this honor and the fact that anything she wears continues to sell out in 24 hours (or less!). The Duchess’ top labels are Sarah Burton for Alexander McQueen, Issa, Jenny Packham, and Alice Temperley.
