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