Prince William, the Prince of Wales, kicked off his four-day visit to South Africa today with a series of engagements that left both locals and royal fans in high spirits.

The royal was greeted by an excited crowd upon his arrival in Cape Town, where he was spotted cutting a relaxed figure as he stepped off the plane.

However, what really stood out during his first day was not just his warm smile but his more casual approach to royal style.

While his wife, Princess Catherine, remained at home in the UK to look after their three children—Prince George, Princess Charlotte, and Prince Louis—William seemed in his element as he embarked on the first leg of his climate-focused trip.

His beaming expression and upbeat demeanor caught the attention of fans, many of whom noted how genuinely happy he looked to be in South Africa.

William’s first official engagement took him to meet young environmentalists involved in the inaugural Earthshot Climate Leaders Youth Program. Addressing the group, he expressed his optimism about their potential, saying, “You are going to change the world.” This inspiring message was met with cheers, as the young environmentalists eagerly soaked in the royal encouragement.

Yet, it wasn’t just his words that sparked conversation—his attire also had fans talking. The 42-year-old royal opted for a sustainable shirt, paired with a smart jacket and trousers, a marked departure from his usual formal suit-and-tie combination. The more laid-back look not only fit the context of his visit but also seemed to reflect William’s evolving sense of confidence and comfort in his royal role.
