Hairnet (5)
I believe the answer is:
snood
'hairnet' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for snood that I've seen before include "Hairnet; headband" , "Loose hairnet" , "Loose cover" , "Nod so violently and it might fall off a girl's head" , "pouch" .)
