Part of Zorro's costume (4)
I believe the answer is:
cape
'part of zorro's costume' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cape that I've seen before include "Florida space flight centre" , "Shoulders? They're covered in it" , "Garment - promontory" , "Cloak; head" , "Cod possibly" .)
