Kate, wife of Charles's elder son Prince William, has previously featured on the cover of Vogue while Meghan, wife of William's younger brother Harry, has guest-edited the magazine.
Charles, who has long campaigned on environmental issues, was interviewed for Vogue about his commitment to sustainable fashion, something he said he had always taken to heart.
“I’m one of those people who hate throwing anything away. Hence, I’d rather have them maintained, even patched if necessary, than to abandon them,” he said, calling on manufacturers and consumers to be less wasteful.
He added: “But it seems to me there are huge opportunities, particularly now, within the whole sustainable fashion sector, to counter this extraordinary trend of throwaway clothing — or throwaway everything, frankly.”
