Hat with a brim (6)
I believe the answer is:
fedora
'hat with a brim' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for fedora that I've seen before include "Or fade away with man's soft felt hat" , "Read of (anag) - brimmed felt hat" , "Headgear" , "Headwear" , "top fashion" .)
