Buckingham Palace followers are sure to recognise the mother-of-three's cream and gold gown from the couple's Diamond Jubilee Tour of Malaysia.
Creative director Sarah Burton was commissioned by the royal to create the bespoke look for a dinner with the King and Queen of the nation.
In a diplomatic fashion move, the dress was embroidered with sparkly hibiscus petals, the national flower of Malaysia.
Bringing the look into the new decade, she accessorised the ensemble with a pair of sparkly Jimmy Choo 'Romy' pumps and a matching clutch bag.
A pair of Van Cleef & Arpel drop earrings were all that was needed to finish the headline-worthy look.
Of course, the royal's legion of fashion followers will not be surprised by her McQueen choice.
Last year, the Duchess of Cambridge reigned the red carpet in a sweeping one-shoulder gown by the British fashion house.
Proving she has always been a thrifty dresser, the 38-year-old chose a pair of pearl earrings, which once belonged to Princess Diana, to complete the look.
