Brimmed hat (6)
I believe the answer is:
fedora
'brimmed hat' 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 "Felt hat dented lengthways" , "Hat for RAF doe" , "Or fade away with man's soft felt hat" , "Cover for head" , "Headwear" .)
