Riches' opposite (4)
I believe the answer is:
rags
'riches' opposite' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rags that I've seen before include "Newspapers" , "Pieces of old cloth" , "Waste scraps of cloth" , "Tattered clothes" , "Tatters or university japes" .)
