Headgear for one at the stag party? (11)
I believe the answer is:
deerstalker
'headgear' is the definition.
(deerstalker is a kind of headgear)
'one at the stag party?' is the wordplay.
'one' becomes 'stalker' (I can't justify this - if you can you should give a lot more credence to this answer).
'at' is a charade indicator (letters next to each other) (I've seen this in other clues).
'the stag party?' becomes 'deer' (I've seen this in another clue).
'stalker' put after 'deer' is 'DEERSTALKER'.
'for' is the link.
Can you help me to learn more?
(Other definitions for deerstalker that I've seen before include "Sherlock Holmes' hat" , "Hunting cap" , "Soft cloth hat" , "Holmes's hat" , "Soft cloth cap; hunter" .)
