With Prince George and Princess Charlotte at home, the Duke and Duchess of Cambridge stepped out for a glamorous night, as the guests of honour for East Anglia's Children's Hospices charity gala.
The swanky affair, A Taste of Norfolk, helped to raise funds for a new hospice, The Nook.
Looking simply flawless, 34-year-old Catherine donned a glittering Jenny Packman gown.
Royal watchers quickly recognised it as the same dress she donned back in 2011 for her very first royal engagement after she tied the knot with Prince William.
The royal couple relished their summer date, with the pair overheard telling five Michelin-star chefs their own cooking experience.

"William has to put up with my cooking most of the time," Kate told the chefs.
Not missing a beat, William quipped, "It's the reason I'm so skinny."
Unlike his usual meals at home, Wills was in for treat at the gala.
Wednesday's menu featured a delicious locally sourced feast prepared by some of the world's top chefs.
The feast included squid ink cracker with Morston smoked salmon made by chef Galton Blackiston (of Morston Hall on the Norfolk coast), scallop ceviche by chef Sat Bains (Restaurant Sat Bains in Nottingham), wild sea bass by Claude Bosi (Hibiscus in London), loin of Houghton venison with summer beetroot purée by Tom Kerridge (The Hand and Flowers in Harlow) and Norfolk raspberries, strawberries, cider and blueberry coulis by Nobu's Mark Edwards.
The exclusive event was hosted by David Cholmondeley, the 7th Marquess of Cholmondeley and his wife Sarah, Marchioness of Cholmondeley, at their country home Houghton Hall in Norfolk.
As the royal patron of EACH, the charity means a lot to Catherine.
The mum-of-two has been royal patron of EACH since January 2012, and her very first public speech in March that same year was for the opening of the Treehouse, a children's hospice opened by the charity.
