The Duchess of Cambridge wore a flowy pink dress, her favourite lace-up espadrilles and a red cross-body bag, while the Duchess of Sussex wore a khaki green V-neck linen midi dress by Lisa Marie Fernandez.
During the family outing, Kate Middleton often held onto Prince Louis, while Meghan cradled two-month-old Archie in a white and yellow blanket, which she later removed as the day heated up.
Royal reporter Rebecca English, who was at the event, tweeted that Prince Louis was "holding [Kate's] hand and toddling around," before writing, "Little Louise [sic] just ran off towards the ponies and Kate had to scoop him up. He’s fast on his feet!"
She added that Kate was also seen trying to get him to wave to dad, Prince William. Meanwhile, Prince George and Princess Charlotte occupied themselves playing kicks with a soccer ball.
Below, the cutest moments from the royal's day out.
