Type of neck fit for woolly (5)

I believe the answer is:

vague

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

'for woolly' is the definition.
(I've seen this before)

'type of neck fit' is the wordplay.
'type of neck' becomes 'v' (I am not sure about this - if you are sure you should believe this answer much more).
'fit' becomes 'ague' (I've seen this before).
'v'+'ague'='VAGUE'

Can you help me to learn more?

(Other definitions for vague that I've seen before include "Not clearly defined or perceived" , "Inexact" , "Uncertain, imprecise" , "Indefinite" , "Indistinct or imprecise" .)

I've seen this clue in The Times and The Sun.
