Dignitaries from around the world attended, creating a sense of unity, while Catherine's presence lent a captivating charm that captivated everyone. As she entered Westminster Abbey, Catherine walked gracefully, but her powerful presence was unmistakable. She looked regal alongside her husband, Prince William, as they took part in the ceremonial procession. King Charles and Queen Camilla led the procession, followed by Princess Anne and the Duke and Duchess of Gloucester. The procession highlighted the importance of this historic occasion. Catherine exuded elegance, making her presence felt quietly but deeply.

Her impeccable fashion choices made a strong impact, but it was her composure at such an important ceremony that truly reflected her understanding of the role of modern royalty. The Princess of Wales has always made good fashion choices. Notably, when she chooses bold red outfits for diplomatic events, they always stand out. On this occasion, she wore a Catherine Walker coat dress, paired with a matching Gina Foster hat. As expected, she accented her look with sentimental jewellery, wearing a diamond and pearl necklace from the late Queen Elizabeth II and matching earrings. In the typically grey weather of March in London, Kate's bright red outfit stood out even more.

Every outfit worn by the royal family has a deeper meaning and symbolism. While Kate isn’t afraid to wear a variety of colors, her choice of red is particularly intentional. Color expert Marina Thomas describes Kate as often wearing red at important events, a nod to her late mother-in-law, Princess Diana. Red symbolizes courage, willpower, and sacrifice, and is rooted in the historical traditions of ancient civilizations. Wearing red shows confidence and a desire to be noticed. Marina also points out the personal reasons behind this color choice; red is associated with love and protection, and is believed by many cultures to ward off negativity. This sends a strong message of unity, strength, and hope to the public.

In fact, red is very versatile and suits almost everyone. Many people avoid wearing it because they feel insecure, which is unfortunate because it suits all skin tones. In addition to her outfit at the Commonwealth Day Service in 2025, Kate also wore a bright red coat when visiting Wales ahead of St David’s Day. A memorable moment came in 2023 when she and William welcomed the president and first lady of South Korea in red. Even for casual get-togethers, like in 2023 at a children’s event, she opted for a trendy red coat. At Christmas, red is a regular choice for Kate; in 2024, she looked stunning in her favourite Alexander McQueen dress. Not only does red resonate with the themes of love, power and courage, it also fits perfectly with the festive spirit.
