and have arrived for tonight's Commonwealth Heads of Government (CHOGM) dinner at the stunning Robert Louis Stevenson's villa in Samoa.
Charles, 75, is wearing a Red Sea rig dress with Samoan detail from the Samoan school of fine art, while Camilla, 77, is in a blue embroidered tunic top and blue palazzo trousers by Anna Valentine with diamond earrings.
It marks their final night in Samoa, having arrived on Wednesday evening, and they are hosting the official dinner and reception to mark the King's first CHOGM since becoming Head of the Commonwealth.
Upon arrival at the villa - which is now a museum dedicated to the late Scottish novelist, the King and Queen were received by the Master of the Household, Vice Admiral Sir Tony Johnstone-Burt.
They then proceeded along the Museum's veranda before greeting the Samoan Prime Minister and Secretary-General of the Commonwealth, Baroness Scotland.
They remained on the veranda to receive Heads of Government and their spouses before moving inside for a reception ahead of dinner.
Two toasts will be proposed by The President of Guyana and The President of Sierra Leone. The King will then deliver some remarks before dinner is served.
Inside guests will sit at round tables featuring a centrepiece of a Tanoa Bowl, napkins printed by EKFS School of Fine Arts and Museum with a traditional Samoan design, and Siapo printed table centres.
Each head of state is given their own silver-filt goblet to toast drim, which has the crest of their own nation emblazed on it. The impressive goblets are only ever used for the biannual event and have been shipped over from London.
The 18 carat gold, silver-gilt, ruby, enamel Commonwealth Mace, which was presented to the late Queen in 1992 on the 40th anniversary of her accession to the throne, was placed on a hand-made table by the EKFS school.
The legs are crafted to symbolize the saying 'We stand on the shoulders of giants' honouring our ancestors.
