Kate Middleton wears Queen Elizabeth’s earrings at Platinum Jubilee

Kate Middleton honored Queen Elizabeth at the Thanksgiving celebrations during the Platinum Jubilee by wearing Her Majesty's Bahrain pearl drop earrings.

The royals brought their fashion A-game to St. Paul’s Cathedral today

for a Service of Thanksgiving in honor of the Queen’s Platinum Jubilee.

The Queen was unable to attend due to mobility issues and “discomfort” after yesterday’s Trooping

the Colour balcony appearance, but her family came out in full force to honor their matriarch.

Kate Middleton looked sunny in a gorgeous yellow dress with a criss-cross waist

a custom piece by Emilia Wickstead — and a matching buttercup colored hat with floral detail by Philip

Treacy as she was joined by Prince William for the tribute to her grandmother-in-law.

She paid homage to the Queen with her jewelry — the duchess borrowed a pair of the monarch’s earrings, wearing her Bahrain Pearl drops.
