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.
