Princess Kate Middleton has nailed the art of gracefully securing her tiara to her hair. Kate, 43, stunned in Queen Victoria's Oriental Circlet Tiara at a state banquet to welcome German President Frank-Walter Steinmeier to the United Kingdom at Windsor Palace on Wednesday, December 3. During the event, the Princess of Wales was photographed from the back, revealing how her tiara stays in place. Her brunette hair was twisted into a tight knot around the piece in a subtle and elegant style. The rest of Kate's mane was styled in loose curls.
