The Princess accessorised this navy look with a pair of stunning saphire and diamond cluster drop earrings. These earrings were an iconic piece of Princess Diana's jewelry and have been worn by Catherine to a number of iconic events, including the Queen's Platinum Jubilee earlier this year.

The Prince and Princess are currently touring Boston ahead of the Earthshot Annual awards ceremony in Boston on Friday, December 2, 2022. The award ceremony is in partnership with the John F. Kennedy Foundation and will celebrate the 2022 winners and finalists of the prize.

The royal couple arrived a few days ahead of this awards ceremony so they can learn a bit more about how Boston is working towards sustainability while building a relationship with the US.

The Princess then had yet another outfit change as she and William joined Governor-Elect Maura Healy and the Mayor of Boston, Michelle Wu to kick off the Earthshot celebrations by lighting up Boston at Speaker’s Corner by City Hall. Kate wore a stunning tartan dress green and navy dress which she paired with a long navy overcoat for a more sophisticated look.
