Brimmed felt hat (6)
I believe the answer is:
fedora
'brimmed felt hat' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for fedora that I've seen before include "Cover for head" , "Headgear" , "Soft hat with band" , "Style of hat" , "O, Fred, a hat becomes you" .)
