Consumer after small women's knitted garment (7)
I believe the answer is:
sweater
'knitted garment' is the definition.
(type of knitted item of clothing)
'consumer after small women's' is the wordplay.
'consumer' becomes 'eater' (consume can mean to eat).
'after' is a charade indicator (letters next to each other).
'small' becomes 's' (abbreviation - e.g. clothes size).
'women' becomes 'w'.
's'+'w'='sw'
'eater' put after 'sw' is 'SWEATER'.
(Other definitions for sweater that I've seen before include "Top" , "Jersey may become" , "Clobber" , "Re waste: it's a garment" , "Guernsey" .)
