The king and queen wore similar shades of royal blue as they led the family into St. George’s Chapel at Windsor Castle.

Sartorially, the Prince and Princess of Wales have been “stepping up a level. If you look back at their trajectory as a couple, for a very long time they were seen as very relatable, very down-to-earth and quite casual. I think what we’ve seen a little bit more of in recent months is them looking much more serious,” like they mean business, said Bethan Holt, author of “The Queen: 70 Years of Majestic Style” and “The Duchess of Cambridge: A Decade of Modern Royal Style.”

Since the queen’s passing in September, the duties and responsibilities of the Princess of Wales have increased along with the ones of Prince William, the heir to the throne.

The Millennial Prince and Princess of Wales have made clear from the start that they want to be modern royals, in touch with their subjects and with the issues of the day. They want to be seen as compassionate change-makers, advocates for British charities and people, and strong parents to their three children.
