In line with religious protocol, Kate dressed demurely for the engagement, in a custom made pale grey dress by eco label Beluah.
The Duchess teamed her long-sleeved, knee-length number with a matching headscarf and delicate drop earrings.
Once inside the royal couple removed their shoes, with Kate slipping off her favourite nude L.K.Bennett Sledge heels to reveal stockinged feet.
Kate has scored a series of style hits since beginning her Far East tour, in dresses by Alexander McQueen, Prabal Gurung, Jenny Packahm and Raoul.
It's thought the Duchess has spent the summer compiling her Jubilee tour wardrobe, sourcing over 30 different outfits for the trip.
