The Duchess of Cambridge watched the Platinum Jubilee Pageant alongside the Duke of Cambridge and their three children from the Royal Box on Sunday.
Kate Middleton arrived wearing a custom fuchsia pink dress by Stella McCartney.
The forest-appropriate raspberry-red viscose custom dress featured padded shoulders, one-shoulder shirring, and long puff sleeves.
The Duchess completed the look with simple gold and diamond earrings, natural makeup and her hair in loose curls.
Kate sat next to her three children, Prince Louis, four, Princess Charlotte, seven, and Prince George, eight, for the pageant.
While George matched Prince William – both were dressed in suits – Louis looked dapper in a black button-up coat with a peter pan collar.
Sitting between her brothers, Charlotte wore an elegant cream coat.
The Platinum Jubilee Competition marks the conclusion of this weekend’s festivities in honor of the Queen’s 70-year reign.
The show began with the Queen’s Gold State Coach being pulled along the Mall by horses and the King’s Troop.
A hologram of the Queen waving to onlookers at her coronation in 1953 was projected on the side of the coach.
More than 10,000 people took part in the show, which consisted of four acts aimed at telling the story of the Queen’s historic reign.
Attendees included the military, over 6,000 volunteers, theater artists, key workers and 2,500 members of the general public.
The pageant marked the Cambridge children’s fourth public appearance during the Platinum Jubilee weekend.
On Saturday evening, George and Charlotte accompanied their parents to the Party at the Palace.
The children were seen smiling and laughing as they watched a sketch of the Queen, their great-grandmother, having tea with Paddington Bear.
They were also seen clapping and singing along with the various musical performances, including Rod Stewart’s rendition of Sweet Caroline.
The young royals also took part in a baking session with their mother, to bake cupcakes for those attending a Jubilee street party in Cardiff today.
Kate shared photos of the family cooking together on Twitter.
One image showed the siblings huddled around a stand mixer. In another, they smiled and giggled as they helped their mom frost the cupcakes.
