Paul Costelloe, the personal fashion designer to Princess Diana, has been remembered by his family as a pivotal figure who helped elevate London Fashion Week. Costelloe passed away last November at the age of 80 following a fall at his home, an incident that was discussed during an inquest at Westminster Coroner’s Court.

The inquest revealed that Costelloe had been living with leukaemia at the time of his death. Despite his health challenges, his contributions to British fashion were widely acknowledged, particularly his influence on runway shows during one of the industry's principal events. Family members emphasized his lasting impact on the fashion world and his close professional relationship with Princess Diana, whose style remains iconic.

Costelloe’s design legacy was marked by a blend of elegance and innovation, helping to shape the aesthetic of British fashion in the late 20th century. His work not only garnered royal attention but also resonated within the broader fashion community, earning him a respected place among leading designers of his era.

The inquest formally recorded his death as accidental, linked to the complications following the fall. Tributes from those close to him underscored his creative spirit and the esteem in which he was held both personally and professionally.
