Kate Middleton Wore Something from Her Wedding Day to Easter Services — and You Probably Missed It

Kate Middleton picked a very special piece from her jewelry box to complete her Easter Sunday look – and give a nod to her eight-year wedding anniversary!

The royal mom of three, 37, joined Queen Elizabeth, husband Prince William, brother-in-law (and soon-to-be dad!) Prince Harry and other members of the royal family for church over the weekend. She wore a perfect springtime look, pairing an Alexander McQueen light blue coat-dress with a matching fascinator by Jane Taylor – an outfit she previously wore to an Easter service back in 2014 during her visit to Australia.

But eagle-eyed royals fans noticed that Kate also sported the Robinson Pelham earrings she wore for her 2011 wedding to William. The diamond sparklers are stylized oak leaves with a pear-cut diamond drop and a suspended diamond acorn at its center. The earrings were specially made to pay homage to Kate’s coat of arms and complement the Cartier halo tiara that she wore for her walk down the aisle.

The choice of earrings was no coincidence – on April 29, Kate and William will celebrate their eighth wedding anniversary.

Before the service at St. George’s Chapel in Windsor Castle, Kate — now a pro at royal protocol — shared a moment with the Queen, putting on a model curtsy.

With one foot behind the other, Kate bent her knees and smiled at the monarch, while also slightly bowing her head — exactly how Myka Meier, founder and director of Beaumont Etiquette says a curtsy should look.

Last year, Meier told PEOPLE that a curtsy should be subtle – and that the deeper and longer you pause shows more respect and formality.
