First Lady Melania Trump and President Donald Trump attended a State Banquet at Windsor Castle on September 17, 2025, hosted by King Charles III and Queen Camilla. The evening honored the long-standing diplomatic relationship between the United States and the United Kingdom, continuing a tradition of formal gatherings that highlight unity and shared history.

Melania Trump stood out in a floor-length canary-yellow, off-the-shoulder gown accented with a lavender belt and statement earrings. The bold color choice drew admiration from many, while sparking some discussion online about its unexpected nature for the royal setting. A celebrity stylist noted that although the look surprised some, it fully aligned with the white-tie dress code, offering a fresh and modern twist within the bounds of tradition.

The banquet itself carried a sense of history, as past events have welcomed leaders such as John F. Kennedy, Ronald Reagan, and Barack Obama. Earlier in the day, Melania showcased a very different look during the ceremonial welcome: a tailored charcoal skirt suit paired with a wide-brimmed hat, which contrasted strikingly with her evening ensemble. The two outfits together highlighted her ability to balance diplomatic formality with individual style.

While opinions varied about her evening gown, the event as a whole underscored the value of tradition, pageantry, and continued cooperation between the U.S. and the U.K. For the Trumps, this marked their second attendance at a State Banquet in Britain, reinforcing their role in supporting international ties and celebrating the cultural and historical bond between the two nations.
