Princess Catherine drew admiration once again for her refined style during the official France state visit to the UK, but it wasn’t just her fashion that caught attention — it was her hair that set social media abuzz.

Dressed in a romantic, blush-toned ensemble by Dior, the Princess of Wales joined Prince William, King Charles III and Queen Camilla to welcome French President Emmanuel Macron and his wife, Brigitte, during their formal visit to London. Her look — carefully curated and rich in subtle royal symbolism — was praised by fashion fans for its softness and grace.

She wore a pale pink tailored blazer in wool and silk, paired with a mesh-overlay pleated skirt that added lightness and texture. Accessories included beige suede pumps, a straw hat with a pastel ribbon, and heirloom jewelry: pearl earrings that once belonged to Princess Diana, a triple-strand pearl necklace from Queen Elizabeth II’s collection, and, of course, her iconic sapphire engagement ring.

But while fashion editors applauded the ensemble, many online turned their focus to Catherine’s cascading, voluminous hairstyle — and speculation soon followed.

Some commenters questioned whether her hair was natural or styled with the help of extensions or wigs. One viewer wrote, “It’s clearly a wig,” while another observed, “Those ends look uneven — definitely looks like a piece.” A few went further, hinting at disbelief over her appearance during cancer treatment. “Crazy how chemo didn’t cost her a strand,” one post read.

Still, others offered a more sympathetic tone. “We don’t know what her treatments are doing to her,” one person commented. “Just happy to see her able to be in attendance.” Another added, “I don’t care if it’s a wig or not — she looks stunning.”

Amid the wave of speculation, fans continued to express admiration. “She looks incredible,” one wrote. “The skirt’s texture is lovely — soft but not too formal. And that hair, wow.” Others praised her signature elegance: “Timeless as always,” said one fan. “A true royal.”

As public curiosity about Princess Catherine remains high following her cancer diagnosis, even small style choices have become subjects of intense online scrutiny. Yet, through it all, her appearance at the state visit seemed to signal strength, grace — and a careful return to public life on her own terms.
