Prince William’s outfit at Pope Francis’s funeral drew attention, though not exactly for the right reasons.

The 42-year-old Prince of Wales attended the funeral on Saturday alongside other world leaders, including Prime Minister Keir Starmer, Donald Trump, and Emmanuel Macron. King Charles was notably absent.

However, not everyone was pleased with William’s choice of attire.

Instead of the traditional black, the father-of-three chose a blue suit for the occasion, something considered unusual for a formal event like this.

He wasn’t alone, though—Donald Trump also wore a blue suit, pairing it with a blue tie. Meanwhile, Ukraine’s President Volodymyr Zelenskyy opted for black military gear rather than formalwear.

“Prince William looked odd with a blue suit and black tie,” one social media user remarked. “Trump completely ignored the black tie instructions.”

Another X user questioned, “What was Prince William thinking about by not wearing a black suit, too? If there’s one thing you’d think the Royals would be red hot on is correct protocol. All he had to do was turn up & look the part. He dropped the ball today.”

“Black tie with a blue suit?” another baffled viewer wrote on X.

Despite the criticisms, the official dress code for the service at St. Peter’s Square in Vatican City called for men to wear a dark suit with a black tie and a black button on the left lapel.

Supporters quickly defended William online by pointing back to the official guidelines.
