Councillor casual and not pressed (6)

I believe the answer is:

creasy

'not pressed' is the definition.
(not pressed with an iron)

'councillor casual' is the wordplay.
'councillor' becomes 'cr' (abbreviation).
'casual' becomes 'easy' (similar in meaning).
'cr'+'easy'='CREASY'

'and' acts as a link.

(Another definition for creasy that I've seen is " Wrinkly".)

I've seen this clue in The Telegraph.
