Kate Middleton—along with her husband Prince William—took part in a ship naming ceremony for the HMS Glasgow in Scotland on May 22. The future queen held a masterclass in literal dressing, wearing a navy and white Suzannah London coatdress and a sentimental pair of heirloom earrings.

Princess Kate, 43, completed her homage to her late mother-in-law, who died in a 1997 Paris car crash, with jewelry from Princess Diana's collection. In addition to their shared engagement ring, the current Princess of Wales donned cabochon sapphire drop earrings that previously belonged to Diana.

Kate's look nodded to her late mother-in-law, Princess Diana. In 1993, Diana attended the 50th-anniversary commemoration of the Battle of the Atlantic in Liverpool wearing an almost identical outfit but with a classic 90s edge.
