Sombrero or fedora, eg (3)
I believe the answer is:
hat
I believe this is a double definition.
'sombrero' is the first definition.
(I've seen this in another clue)
'fedora eg' is the second definition.
(fedora is a kind of hat)
(Other definitions for hat that I've seen before include "Head-covering" , "Cloche or fez?" , "Accessory" , "Headdress" , "Headgear decoration" .)
