Rewards fashion designers (7)
I believe the answer is:
drawers
'designers' is the definition.
(I've seen this before)
'rewards fashion' is the wordplay.
'fashion' indicates anagramming the letters.
'rewards' with letters rearranged gives 'DRAWERS'.
(Other definitions for drawers that I've seen before include "Underwear (for artists?)" , "Could be a chest of them but they're worn lower down" , "Old-fashioned clothes" , "undergarment" , "pants" .)
