In the lavish world of high fashion, dresses are more than just garments; they are symbols of cultural moments, embodiments of artistic vision, and occasionally, artefacts of historical significance. This allure often translates into astronomical values when these dresses find their way to the auction block.

Earlier this month a black and blue velvet evening dress once owned by Princess Diana sold for a record-breaking £900,000 ($1.14 million) designed by Jacques Azagury, it is a romantic ballerina-length evening dress worn by the late Princess in Florence in 1985 and Vancouver in 1986. After fetching the astronomical bid at Julian's auction in Hollywood, it leaved us to wonder what other royal and A-list fashion statements have been sold for a hefty price tag in recent years.

Princess Dianas ‘Travolta’ dress

Possibly one of the most well-photographed dresses in modern history, Diana donned a floor-length black velvet gown while attending a state dinner in 1985.

When the dress first went to auction in 2019 it failed to reach its £200,000 reserve price but was later sold to Historic Royal Palaces for £264,000.

Princess Diana’s Jacques Azagury evening dress
