Clothing industry (3,5)
I believe the answer is:
rag trade
'clothing industry' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for rag trade that I've seen before include "Fashion industry (informal)" , "The fashion business" , "newsagent's business?" , "Informal description of clothing industry" , "Clothing business (colloq.)" .)
