Sweater, jumper (8)
I believe the answer is:
pullover
I believe this clue is a double definition.
'sweater' is the first definition.
(I know that pullover is a type of sweater)
'jumper' is the second definition.
(I know that pullover is a type of jumper)
(Other definitions for pullover that I've seen before include "top gear?" , "Sweater or jumper" , "Woolly" , "Jersey" , "Go to side of road" .)
