I believe the answer is:
coco
'chanel of fashion' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for coco that I've seen before include "address for Chanel" , "French fashion designer, who branched into perfume etc" , "'... the Clown, ... Chanel (4)'" , "Gabrielle Bonheur Chanel" , "Famous clown" .)
