Duchesses Kate and Meghan proved it is all about the hats as they stepped out with their husbands and other members of the royal family to celebrate Commonwealth Day.
Kate, the Duchess of Cambridge, color-blocked in a red Catherine Walker coat paired with a red hat.
Meghan, the Duchess of Sussex, paired her white coat, reportedly by designer Victoria Beckham, with a white hat.
The sisters-in-law joined their spouses, Prince William and Prince Harry, at Westminster Abbey for a Commonwealth Day Service with Queen Elizabeth II, Prince Charles and Camilla, the Duchess of Cornwall, and Prince Andrew.
Meghan was seen talking with Kate and sharing a laugh with Prince Charles at the service, which celebrates the 53 Commonwealth countries around the world.
Prior to the service, Prince Harry and Meghan, wearing an embellished green coat dress reportedly by Erdem, made a visit to Canada House in London.
