On Jan. 5, Kate Middleton and Prince William joined Queen Elizabeth II for a Sunday church service in Sandringham. At the recent outing, the specific fashion choices made by the Duchess of Cambridge caught the attention of royal watchers.

According to Express, Kate wore a "bold plum and orange coat paired with a deep blue fedora." This mimicked the fact that the monarch also wore purple. However, hers was a more vibrant shade.

As stated by the outlet, the Duchess' style decision "sent a strong royal message" as purple is a color that is often associated with members of the British royal family. Therefore, it not only had a deep historical significance, but also "hinted" at Kate's future role within the famous family. It was also revealed that Kate's blue hat gave a nod to Her Majesty as she herself is known to wear blue quite frequently for a particular reason.

Additionally, it was stated that the Duke and Duchess of Cambridge's presence was a "clear show of support for the Queen at the start of the new year."
