The Princess of Wales has turned color into a quiet form of diplomacy. Over the years, the British royal has mastered the art of flag dressing, transforming the shades of a country's colors into a fashion statement. That particular type of dressing is "one of the most immediate visual signals and is a form of sartorial diplomacy," British fashion designer Amanda Wakeley OBE explains to HELLO!, but "it's rarely handled in a literal way".
"The sophistication comes through interpretation, subtle shifts in tone, fabric, and cut. It's highly intentional, but always balanced so it never feels overly obvious or contrived," Amanda says. "This practice serves as a visual gesture of respect and solidarity toward a host country or a visiting nation during official state events."
Catherine exemplified this at the Nigerian state banquet in March 2026, when she stepped out in a billowing gown by Andrew GN. The green hue of the design, paired with matching Manolo Blahnik pumps, was no doubt a nod to Nigeria's national flag.
"By incorporating the colours of the Nigerian flag into her eveningwear, she’s signalling respect, awareness and cultural alignment without needing to say a word. It's a thoughtful, strategic approach to dressing that reinforces her role on the global stage," luxury fashion stylist Oriona Robb tells HELLO!.
Amanda notes that the Princess' choice to dress in a country's colors is almost always about more than a simple styling decision.
"It operates as a quiet form of soft power, it's considered, respectful, and immediately understood without needing explanation. Fashion in that context becomes a diplomatic tool, but one that feels effortless rather than staged," she says.

In moments of flag dressing, the Princess' color choices are far from coincidental. "They come across as thoughtful acknowledgements rather than bold statements," Amanda says. "It's a very measured way of signalling awareness and respect, without ever tipping into anything overt."
Oriona observes that what is particularly effective is the seamless execution of each look, which never feels "costume-like". Instead, they are "refined, elegant and entirely in keeping with her personal aesthetic," Oriona says. "That balance is crucial, when done well, flag dressing should feel like a nod rather than a statement piece, and the Princess consistently gets that nuance right."
"More broadly, this style of dressing reflects a modern evolution of royal fashion. It's no longer just about looking appropriate or polished, it’s about fashion storytelling and connection," Oriona continues. "In moments like this, fashion becomes a quiet bridge between cultures, and the Princess of Wales is using it with increasing confidence and sophistication."
At a certain point, a shade stops being just a beautiful color and starts to become a message, as we've seen with Catherine's flag dressing. "It shifts when context gives it meaning. The same outfit in a different setting might simply feel elegant, but in the right moment, it can communicate recognition or alignment," Amanda says. "Timing, audience, and intention all play into that shift, especially with someone who is on a global stage and in the spotlight consistently."

Catherine's fashion choices suggest a "very considered and thoughtful approach" to her role. "She understands the influence she carries and uses fashion to support that role rather than overshadow it. There's a clarity and restraint in how she presents herself, which gives her choices a quiet authority," Amanda says.

"I think she uses fashion with clear intention, but never in a way that feels calculated for its own sake. It comes across as instinctive and grounded in a strong understanding of both her role and the language of clothing," Amanda says.
"That balance is what makes it so effective. Like it or not, her choice of clothes will always be analysed, and they are a powerful tool for her to communicate with," Amanda adds. "And let's not forget her unofficial role as a global ambassador for British Fashion. What she wears not only gets noticed, it gets sold, which is wonderful for the British Fashion industry!"
