Princess of Wales Kate Middleton is back on parade celebrating King Charles‘ first birthday parade since becoming monarch.

Many members of the royal family attended the yearly celebration of King Charles’ first birthday, including his daughter-in-law, who accompanied Queen Camilla in a horse-drawn carriage.

Prince George, Princess Charlotte, and Prince Louis, Kate’s three children, joined her in the coach, just as last year.

As Colonel of the Welsh Guards, Prince William rode into the parade as the regiment whose “colour,” or flag bearing the honors of the regiment, will be delivered to the King this year. William, who turns 41 on Wednesday, was decked out in his official bearskin headgear and high-ranking honorary officer suit.

Queen Camilla and Princess Kate joined the other Royal Colonels as the Welsh Guards presented the King with their flag, or “colour,” when the procession arrived at Horse Guards’ Parade. Previously, both royal ladies and other royals would observe this portion of the ceremony from one of the structures encircling the parade grounds.

Princess Kate wore a hat by Philip Treacy and a dress by Andrew Gn, a fashion designer from Singapore. Prince William’s Earthshot Prize, whose new awards ceremony will take place in the Asian nation in November, was clearly referenced by the outfit choice. It was a vivid green, which was perfect for the environmental endeavor.

The color selection is also significant because it is one that appears in the Welsh flag; William and Kate were made Prince and Princess of Wales following King Charles’ accession to the throne.

The flypast for Trooping the Colour on Saturday will feature over 70 aircraft from the Royal Navy, British Army, and Royal Air Force. It will be Charles’ first birthday flypast.

However, poor weather may cause the lengthy military flypast to be shortened.

The King, Queen, and other royal family members are anticipated to watch as the planes perform a six-minute performance over The Mall and Buckingham Palace.
