Duchess Catherine with Princes William and Harry

Britain's Duchess Catherine and Prince William attended a close friend's wedding on Saturday (30.03.14).

The royal couple were joined by flame-haired Prince Harry at St. Mary's Church in Chippenham, south west England to celebrate Lucy Meade and Charlie Budgett's nuptials.

Lucy is the sister of James Meade, one of the Duke of Cambridge's school friends from Eton, and the best man at the Royal wedding.

The Duchess of Cambridge - known as Kate Middleton before she married into the Royal Family - wore a blue overcoat with a navy fascinator and heels, while the brothers opted for three-piece suits with coat tails.

The Duchess has worn the coat before, she was spotted wearing it at Fortnum and Mason during a visit with Queen Elizabeth and Duchess of Cornwall in March 2012 and was seen wearing the piece in Nottingham three months later at the queen's Diamond Jubilee celebrations.

The young couple appeared to have left eight-month-old Prince George at home but the tiny tot will be joining them for their Australia and New Zealand tour next month.
