So Don refashioned the fillet (5)

I believe the answer is:

snood

I'm a little stuck... Click here to teach me more about this clue!

'the fillet' is the definition.
(I've seen this in another clue)

'so don refashioned' is the wordplay.
'so don' can be anagrammed to 'SNOOD'.
Though, I am not sure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for snood that I've seen before include "Loose cover" , "Ornamental hairnet" , "Hairnet; headband" , "Nod so violently and it might fall off a girl's head" , "Loose hairnet" .)

I've seen this clue in The Irish News.
