His agent, Pete Bassett, said he would be remembered as "a hard-working, very amusing and lovable individual who always was at the forefront of fashion trends".
"Up until last year he was putting together a book of fashion styles based on the New Romantic movement and it comes as a great shock.
"We understood that he had certain health problems but nothing we knew was life threatening.
"His friends and family are totally shocked, we had no idea anything like this was likely to happen."
