A quiet fellow has kitchen attire (5)
I believe the answer is:
apron
'kitchen attire' is the definition.
(I've seen this in another clue)
'a quiet fellow' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'fellow' becomes 'ron' (masculine given name).
'a'+'p'+'ron'='APRON'
'has' acts as a link.
(Other definitions for apron that I've seen before include "Protective garment worn at front" , "that's used by Oliver!?" , "Projecting stage" , "Kitchen garment or airfield area" , "standing" .)
