Alongside his acting roles, Peter Wyngarde was known as the best-dressed man in Britain.
He beat singer Cliff Richard and football star George Best to the award in the 1970s.
On TV, he was famed for his role as suave womaniser and writer turned sleuth Jason King.
And the actor said that, when it came to his wardrobe, it was “difficult to separate” him from his famously flamboyantly dressed character, with his moustache, frilly shirts and wide-lapelled three-piece suits.
He once said that it had “cost me a small fortune” to have his suits and overcoats made.
His character is said to have inspired actor Mike Myers’ look for Austin Powers.
And on Twitter, fans have been remembering the actor’s dress sense.

So Peter Wyngarde has sadly passed away. My main recollection of him is of course Jason King of Department S. He was also satirised brilliantly in my favourite Comic Strip Presents episode, Detectives on the edge of a nervous breakdown, by Peter Richardson. Indeed deedy pic.twitter.com/g7fm36RMIw

Oh, Peter Wyngarde. To me, you’ll always be the menacing, silky-voiced Klytus, forever saving Ming the Merciless from boredom. An extraordinary performance in an amazing film. RIP. #FlashGordon pic.twitter.com/bwApKDg9p8

Actor and screenwriter Mark Gatiss was also among those to pay tribute.
From wartime internment alongside JG Ballard to Klytus. With No.2, Baron Gruner, Professor Norman Taylor, Peter Quint and Gloucester bus station in between. What a life. What a legend. Jason King is dead. Long live Jason King! #peterwyngarde pic.twitter.com/GX6AENMRZY
