Confident and stylish (8)
I believe the answer is:
debonair
'confident and stylish' is the definition.
This is the entire clue.
(Other definitions for debonair that I've seen before include "Having a carefree confident manner" , "(Of man) stylish, charming" , "Sprightly" , "Bored Ian can have carefree appearance" , "Elegant, courteous" .)
