Stated couple settles for partial head coverings (7)
I believe the answer is:
toupees
'coverings' is the definition.
(toupee is a kind of covering)
'stated couple settles for partial head' is the wordplay.
I cannot quite understand how this works, but
'for' could be 'to' (eg both can mean 'in the opinion of') and 'to' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for toupees that I've seen before include "Sue poet having American wigs" , "Small hairpieces" , "Wigs for American men" .)
