Suave and sophisticated (6)
I believe the answer is:
urbane
'suave and sophisticated' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for urbane that I've seen before include "Unbare, being suave." , "Suavely elegant" , "Smooth" , "Elegant and sophisticated - sounds like city type" , "Smooth-mannered" .)
