Harry impeccably modeled the red, white, and blue headdress -- the colors of the British flag -- keeping his hands on his hips while accessorizing with a matching traditional necklace and his own Ray-Ban sunglasses.
While Harry displayed his British pride in the Caribbean, his girlfriend, Meghan Markle, seems to have passed down a little U.K. love to her dog, Guy.
"For the love of hand-me-downs. This was Bogart's sweater when he was a puppy, and now it's keeping Guy warm," she captioned the cute pic, adding the hashtags, "#puppylove," "#adoptdontshop," and "#reducereuserecycle."
