Mr Humphreys always looked/looks great.
In fashion of the times some of the stuff was a bit extreme but rarely bad. He (the character at least) paid attention from head to toe. I still enjoy watching just to see his clothes. And the Carry On lines.
Did he dress himself and was Inman the person as well dressed off the show?
"I really like that colour/pattern combo he's wearing - it seems simple yet would be challenging to get right"
Precisely.
I don't know about icon, but irrepressible and hard to ignore ...
