Prince Philip took a 51-year-old pair of trousers to a tailor to be altered recently.
The royal ordered the baggy 50s-style garment be changed into something more contemporary by Savile Row tailor John Kent of Norton & Sons.
The trousers belong to a suit made of hard wearing worsted cloth, which has a striking grey and brown herring-bone stripe, and have now been re-fashioned into slimmer legs.
Patrick Grant, one of the company’s directors, is quoted in The Daily Telegraph as saying: “John has been making the prince’s clothes for many years and has a royal warrant.
“About six weeks ago, the prince sent him a pair of trousers that he wanted re-cutting to give a slimmer, more fashionable look.
“The prince likes substantial cloth. He certainly gets plenty of wear out of all his clothes.”
The prince appeared at number 33 in a list of Britain’s best-dressed men compiled by GQ magazine recently.
He is renowned for keeping favourite items of clothes for years and attends naval ceremonies in the uniform he wore at his wedding in 1947.
