Princess Kate has honored the mother-in-law she never met, Princess Diana, in a number of ways through the years. Whether it's channeling the late princess in a very similar mint green blazer or wearing Diana's iconic sapphire engagement ring,

Lady Diana Spencer was originally given this pair of earrings 44 years ago, ahead of her wedding to Prince Charles.

This afternoon, the Princess of Wales recycled a Catherine Walker dress for the annual Commonwealth Day Service—paired with jewels that carried a deeper meaning.

Middleton wore a Catherine Walker coatdress in a shade of bright red with a twisted bow effect near the neckline. The slim-fitting dress featured circular buttons down the front placket and sharp shoulders with long sleeves and a midi length.

The Princess of Wales paid homage to both women through her thoughtful jewelry choices on March 10. Kate Middleton often pays homage sartorially to her late mother-in-law Princess Diana, including at today’s Commonwealth Day service.
