Repair tears and sew garments (8)
I believe the answer is:
sweaters
'garments' is the definition.
(sweater is a kind of garment)
'repair tears and sew' is the wordplay.
'repair' is an anagram indicator.
'and' says to put letters next to each other.
'tears'+'sew'='tearssew'
'tearssew' anagrammed gives 'SWEATERS'.
(Other definitions for sweaters that I've seen before include "Jumpers or pullovers - make you perspire" , "Jerseys, pullovers" , "Knitted upper garments" .)
