Despite the bold fashion choice, Kate’s behavior followed traditional royal protocol. She greeted Queen Camilla with a kiss on each cheek and curtsied to King Charles, maintaining the poise expected at such events.

This contrast made the outfit stand out even more — a modern, slightly daring look within an otherwise formal and familiar royal setting.

Mixed reactions online

Online came quickly, and not all of it was positive. Some critics were blunt in their assessments.

“Looks like air hostess,” one wrote. Another added, “Looks like a uniform.” A third said, “No definitely not her best look [sic].”

Others echoed similar sentiments, with comments like “Kate looks like stewardess” and claims that the outfit appeared “matron” or “Makes her look old.”

Such criticism stood out because Kate’s style is usually praised for being polished and flattering, making this backlash more noticeable than usual.

Supporters defend the look

At the same time, many fans came to her defense. “So elegant no matter what she wears,” one supporter wrote. Another added, “Always elegant & beautiful!” while a third described her as “Stunning in that color . My goodness ❤️[sic].”
