Most of the royals were dressed in matching shades of blue, which palace sources described as a coincidence.
The Queen Consort chose a navy Anna Valentine outfit, who created her wedding gown when she married then-Prince Charles in 2005, and a Philip Treacy hat.

This year's Easter Sunday marked the King and Queen's 18th wedding anniversary.
Pinned to the Queen Consort's coat was the late Queen Elizabeth II's diamond love knot brooch.
The Princess of Wales wore a blue coat by Catherine Walker and a hat by Lock & Co.
Princes William and Prince George wore matching navy suits, while Princess Charlotte had on a blue polka-dot dress.

The service, which started at 10.45am lasted an hour.

The Queen Consort left separately because she had a private engagement to attend but took a posy of flowers from a young girl waiting outside, telling her: "A very, very happy Easter. What a beautiful day".
As the King left following refreshments with the Dean, he was cheered loudly by the crowds.
