One day after the Sussexes celebrated their seventh wedding anniversary, the Princess of Wales wore an accessory from their big day to a Buckingham Palace garden party.

Perhaps the most touching detail about the princess's garden party look was her earrings. She was wearing the same diamond drop earrings that she wore on her wedding to Prince William in 2011. Per InStyle, the earrings were a gift from her mother, Carole Middleton, and designed to resemble the Middleton coat of arms, with oak leaves and acorns.
