The 32-year-old mum looked casual and happy in a breton-striped shirt which she paired with skinny jeans, sneakers and oversized sunglasses. Kate wasn't the only one who looked adorable in stripes -- George wore a baby blue onesie and an adorable blue and white striped bucket hat. We can't get over how cute the future king is.

Kate and George joined the Middletons in Mustique for their annual family vacation. However, Prince William was noticeably absent -- he reportedly stayed back in the U.K. to attend his courses at Cambridge University.

Prince George's first transatlantic flight should help prepare him for his big upcoming trip in just a couple of months. In April, he'll join his mum and dad on a tour of New Zealand and Australia.

According to the Daily Mail, by the time the little prince is nine months old, he will have already travelled nearly 65,000 kilometres.

Meanwhile, the Duchess is due back in London next Tuesday to attend an event at the National Portrait Gallery. We wonder if she'll be debuting her new "subtle but significant regal makeover?"
