What do you think of Kate's style?
Prince William's much-admired wife celebrates her 31st birthday today, and in honour of the occasion, the keys to Catherine's fashion stardom have been compiled by style bible Vogue.
The high-fash rag has analysed 100 of the now pregnant Duchess of Cambridge's fashions since she joined the royal family in April 2011, and have concluded that to be a true copy Kate, one should wear blue, carry a clutch bag with both hands, and tilt hats to the right at 50 degrees. Dresses sell out within hours of Catherine wearing them, while salons are bombarded with requests to match her brunette blow-dry curls.
