The luxurious wool fabric featured six large buttons, cuff-length sleeves, handy pockets, a front slit and a stylish Mandarin collar. The red of her dress matched the dragon on the Welsh flag, adding meaning to her look. She paired the dress with deep navy Gianvito Rossi heels and a new navy Demar Nano Montreal leather handbag. Her gold-toned hoop earrings completed her stylish outfit.

Princess Charlotte, who has already won the hearts of royal fans, also looked adorable. She wore a navy coat with a classic Peter Pan collar over a blue and white patterned dress. Her hair was down, with some strands elegantly braided, and she wore white socks with matching Mary Jane flats. Prince William joined them, wearing a navy blazer over a light-coloured button-down shirt, dark trousers and lace-up shoes. George matched his father's outfit, and the family posed for photos, happily linking arms as they arrived at the castle.

William and Catherine instructed their children to shake hands with dignitaries, helping them practice introductions during the important visit. Although Charlotte appeared shy at first, she quickly brightened up, enjoying the opportunity to meet the crowds. The outing was one of the young royals' first official appearances in Wales, giving the public a chance to mingle with the future king and queen.

Charlotte waved to well-wishers, holding hands with her mother, while Catherine smiled at the crowd. Meanwhile, Prince George looked confident as he stood next to his father, who affectionately placed his hand on George's shoulder, showing off their close bond. George looked happy as his father guided him through the event. One particularly sweet moment saw George running a technical desk while Charlotte happily conducted the musicians, beaming with excitement.

The family listened to an orchestra play popular songs, including 'Sweet Caroline', but it was the song from 'Encanto' that really got Charlotte going, sending her swaying with joy. The visit ended with Charlotte and George receiving flowers from the public, showing off their growing royal responsibilities. With each appearance, Catherine and William continue to teach their children about royal life.

This surprise trip to Cardiff Castle created another unforgettable memory for the Welsh family. The trip gave them a unique opportunity to connect with the people of Wales, and their coordinated outfits symbolised their unity and love for the country. Crowds greeted them warmly as the young royals took a significant step towards their future roles in the monarchy.
