The Duchess of Cambridge's love of headbands continues!

The latest addition to her collection is the 'Calypso Halo' by Jane Taylor, a piece in "iconic British tweed" that Duchess Kate wore to the Anzac Day service at Westminster Abbey.

The annual service—which Prince Williamalso attended—honors citizens of Australia and New Zealand who have served and died during wars, conflicts, and peacekeeping operations.

Kate's £830 ($1054) headband was tied by a large black satin bow at the back of her head, a detail that Kate echoed in her choice of accessories: black pumps and a black clutch.

However her overall ensemble was mainly off-white: the tweed headband and a coatdress by Alexander McQueen that Kate has worn on several other occasions, including her daughterPrincess Charlotte's christening in 2015.

She also wore the pearl drop earrings that once belonged to Princess Diana.

Accompanying Kate to Easter service at Windsor Castle were her husband William and their two oldest children Prince Georgeand Princess Charlotte.
