Kate Middleton glows in blue Catherine Walker for Anzac Day

Beautiful in blue! 

The Duchess of Cambridge stepped out on Thursday morning in honor of Anzac Day to honor the sacrifices of New Zealand and Australia's fallen soldiers. The royal was joined by dad-to-be Prince Harry and the Duke of Gloucester at Westminster Abbey to mark the occasion with a service. 

For the occasion, the mom-of-three opted for a new teal coatdress by one of her go-to designers Catherine Walker. She paired the look with a matching feathered hat, Kiki McDonough jewelry and forest green Emmy London heels.

It's been a busy few weeks for the royal family, who will welcome the newest royal "any day" now

Despite the Duke of Sussex's surprise appearance on Thursday, neither Duchess Meghan nor Prince William were in attendance for the day of remembrance. The Duke of Cambridge is currently in New Zealand for Anzac Day and to pay his respects to victims of the Auckland Christchurch attacks, while Meghan is preparing for Baby Sussex.

The family also celebrated Prince Louis' first birthday on Tuesday by marking the occasion with new public photos. The adorable shots were captured by the Duchess of Cambridge earlier this month. 

For more on the holiday, watch the video above.
