The sweaters knitted for lovers (11)
I believe the answer is:
sweethearts
'lovers' is the definition.
(sweetheart is a kind of lover)
'the sweaters knitted' is the wordplay.
'knitted' is an anagram indicator (knit can mean to screw up or crease).
'the'+'sweaters'='thesweaters'
'thesweaters' anagrammed gives 'SWEETHEARTS'.
'for' acts as a link.
(Other definitions for sweethearts that I've seen before include "lovers" , "Loves" , "They love" , "darlings!" .)
