Suave, refined (8)
I believe the answer is:
debonair
I believe this is a double definition.
'suave' is the first definition.
(I know that suave can be written as debonair)
'refined' is the second definition.
(similar in meaning)
(Other definitions for debonair that I've seen before include "Confident, stylish and charming" , "Chic" , "Bored Ian can have carefree appearance" , "Of good appearance and manners" , "I broaden out, being self-confident and carefree" .)
