Marking just the third time the Duchess of Cambridge has worn a tiara, Kate chose her late mother-in-law, Princess Diana's crown to wear to the largest annual reception at Buckingham Palace.
Arriving at the Queen's annual Diplomatic Reception, Kate was snapped wearing the glittering diamond and pearl Cambridge Lover's Knot tiara, once owned by Diana.
It is also speculated that she paired it with a recycled Alexander McQueen dress from last year's event.
