Sombrero or beret (3)
I believe the answer is:
hat
This clue is a double definition.
'sombrero' is the first definition.
(I've seen this in another clue)
'beret' is the second definition.
(thesaurus)
(Other definitions for hat that I've seen before include "Bowler maybe" , "Cap" , "Item of headgear" , "Eg, bowler" , "e.g. Pork pie" .)
