The royal removed the belt from the designer jacket for a more relaxed feel but cinched in her waist with a brown belt over the top of her recycled 'Seymore'  dress from Gabriela Hearst which featured a rounded neckline and a floaty skirt.

To accessorise her look, the mother-of-two popped on a pair of dark brown leather boots with the 'Nuschi' bag from Sophie Habsburg - a deep green snakeskin number.

The star of the show was her Hermès silk twilly scarf which dressed up her low ponytail which added a vibrant touch to her muted look.
