The Kate Middleton Look Book

Long before she became Duchess Catherine, Kate Middleton built a reputation as a young, chic, and quintessentially British dresser. Her preppy coats, occasional tweeds, unfussy dresses, and natural good looks quickly won over Valentino and Karl Lagerfeld, while the occasional hats she wears to weddings (or the races) keep her adoring public guessing. When she forged a relationship with Alexander McQueen's Sarah Burton, who designed her world-famous royal wedding dress, she earned her stripes with high-fashion aficionados; meanwhile, her loyalty to high street brands like Topshop and Zara has continuously won her favor with the public.
