Suave and refined (8)
I believe the answer is:
debonair
'suave and refined' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for debonair that I've seen before include "Light-hearted" , "Suave and refined" , "Cheerful, charming and elegant" , "Having a carefree confident manner" , "self-assured" .)
