Kate Middleton is adding a bit more sparkle and shine to her evening look. As the Duchess of Cambridge arrived for the annual evening reception for the members of the Diplomatic Corps at Buckingham Palace, fans may have first laid eyes on her stunning Jenny Packham gown, E! News reports. And yes, she absolutely recycled the look after wearing it at a China State Dinner.

The accessory was the Cambridge Lover’s Knot, one of the most well-known tiaras from Princess Diana’s collection.
