Duchess Catherine is undoubtedly one of the world’s biggest style icons.
Whenever she steps out for a royal event, literally thousands of people will go into full-blown research mode to find out where she acquired her outfit.
But we can’t forget the beautiful brunette from Bucklebury’s fashion origins.
Then known to the world as Kate Middleton, Prince William’s leading lady started the noughties as a fresh-faced 18-year-old, and ended the decade in style with a glittering engagement ring on her finger.
Noughties style may not be as iconic an era as say the swinging sixties or eclectic eighties, but Kate’s fashion choices will certainly go down in history.
From shrug tops to flared jeans, the Duchess of Cambridge’s wardrobe was full of clothes that defined the decade that was the 2000s.
