Princess Charlotte Went Nautical Chic at the King’s Cup Regatta

Surprisingly, Princess Charlotte’s Peter Pan collared A-line dress is still available online and on sale for $109. The charming  frock also features a pleated skirt and delicate white buttons down the back.

Charlotte kept her accessories to a minimum and simply paired the look with a pink hair tie worn on her wrist.

Before the event began, Princess Charlotte took a moment to indulge in typical 4-year-old behavior and stuck her tongue out at the crowd.

She and Prince George, who also opted for a blue and white striped getup, spent the rest of their afternoon watching their parents serve as skippers on competing boats in the King’s Cup. They also hung out with their grandparents, Mike and Carole Middleton (who also wore blue and white stripes). Prince Louis was noticeably absent from the high seas and was likely kicking back and relaxing at home with the family nanny,Maria Teresa Turrion Borrallo.

Princess Charlotte might be a mere preschooler, but she’s quickly learning the fashion icon ropes.
