Belt for clothes (7)
I believe the answer is:
clobber
I believe this clue is a double definition.
'belt' is the first definition.
(thesaurus)
'clothes' is the second definition.
(clobber can mean one's clothing)
'for' acts as a link.
(Other definitions for clobber that I've seen before include "Clothes; to beat, criticise (slang)" , "Clothes and accessories" , "what one barely lacks" , "Lick" , "Flog" .)
