More than 25 years after her tragic passing, Princess Diana remains one of the most beloved figures in modern royal history. And this week, her enduring influence was felt once again — not through a public appearance or documentary, but through a rare auction that brought personal pieces of her life back into the spotlight.

Held at the Peninsula Hotel in Beverly Hills on June 26, the event featured more than 140 items from Diana’s wardrobe. The auction, titled “Princess Diana’s Style & A Royal Collection,” drew collectors, fashion historians, and royal admirers from around the world.

Among the most anticipated pieces was the floral Bellville Sassoon dress affectionately known as the “Caring Dress,” which sold for an astonishing \$520,000 — more than double its estimate. The late designer David Sassoon created the piece for Diana during the height of her royal duties, and she often wore it during hospital visits.

“It was soft, colorful, and made her look approachable,” said Martin Nolan, co-founder of Julien’s Auctions. “Children loved it, patients felt at ease — it captured the kind of warmth Diana brought with her wherever she went.”

Another standout was a pale blue Catherine Walker evening gown worn during a 1986 diplomatic tour in the Gulf. It fetched \$450,000. Several handwritten notes and greeting cards — some co-signed by her sons, Princes William and Harry — also drew attention. A personal letter to a palace staff member sold for \$6,500.
