The Duke and Duchess of Cambridge joined the Queen and other members of the British Royal Family for Easter Sunday service at St. George’s Chapel.
This was the couple's third consecutive year to attend the Easter celebrations at Windsor Castle.
Here is a look back at their past attendances:
The Duchess looked elegant today in her dove grey ensemble from Alexander McQueen which she first wore for an Easter Sunday church service at St. Andrews Cathedral in Sydney during the Royal Tour of Australia in April 2014.
The custom coat has a silhouette based on a design from an earlier Alexander McQueen collection. The tailored coat has a funnel neck, concealed front fastening, structured shoulders, cropped sleeves, inset pockets to the sides, a rear vent and a straight hem. It is made from a acetate/rayon blend.
Kate again teamed the coat with her grey Jane Taylor ‘Lupin’ velour felt teardrop beret.
Kate accessorized with her favourite Emmy London styles in a Steel grey colourway. She carried the 'Natasha' clutch (£350), and on her feet were the 'Rebecca' pointed high-heel court shoes (£425).
The highlight of the outfit were the Robinson Pelham diamond acorn drop earrings.
This is just the third time they have been seen in public since Kate first wore them to her 2011 wedding. You may recall she also wore them in 2016 for the Order of The Garter Service.
The earrings were custom-made for the wedding and they were a gift from her parents, Michael and Carole Middleton. The design of the diamond earrings was inspired by the family's new coat of arms that includes acorns and oak leaves.
Kate complemented the earrings with her oak leaf and acorn brooch.
We first got a glimpse of it at the Queen's Jubilee luncheon in 2012, and again on Christmas Day in 2015.
