Woollen garments (8)
I believe the answer is:
knitwear
'woollen garments' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for knitwear that I've seen before include "sweaters, for example" , "Woollens" , "'Woolly jumpers, socks etc (8)'" , "Sweaters and suchlike" , "Sweaters etc" .)
