PAUL COSTELLOE, the former personal fashion designer to Diana, Princess of Wales, has died at the age of 80.
A statement from his family revealed the Irishman passed away on Friday following a short illness.
"He was surrounded by his wife and seven children and passed peacefully in London," it added.
Born in Dublin in 1945, Costelloe studied at the city's Grafton Academy of Fashion Design.

He set up his own label, Paul Costelloe Collections, in 1979.
In 1983, Costelloe was appointed as the personal designer to Princess Diana, with the successful collaboration continuing until her death in 1997.
He was first invited to show at London Fashion Week in 1984 and became a staple of the trade show over the following decades.
Last month, he was the closing designer for the inaugural Irish Fashion Week.
For the past two decades, Costelloe worked with Irish retailer Dunnes Stores and developed corporate wear for organisations including British Airways, Delta Airlines and the Irish Olympic Team.
