Consumer's after second women's garment (7)
I believe the answer is:
sweater
'garment' is the definition.
(sweater is a kind of garment)
'consumer's after second women's' is the wordplay.
'consumer' becomes 'eater' (consume can mean to eat).
'after' is a charade indicator (letters next to each other).
'second' becomes 's' (common abbreviation).
'women' becomes 'w' (standard abbreviation).
's'+'w'='sw'
'eater' put after 'sw' is 'SWEATER'.
(Other definitions for sweater that I've seen before include "Jumper or jersey" , "A present from Mum!" , "Jumper (7)" , "Clobber" , "person in a sauna?" .)
