Rough and ready fashion garment (9)
I believe the answer is:
makeshift
'rough and ready' is the definition.
(I've seen this before)
'fashion garment' is the wordplay.
'fashion' becomes 'make' (fashion can mean to make or create).
'garment' becomes 'shift' (shift is a kind of garment).
'make'+'shift'='MAKESHIFT'
(Other definitions for makeshift that I've seen before include "temporary expedient" , "crude arrangement" , "temporary measure" , "Serving as a temporary and less adequate substitute for something" , "Interim, temporary" .)
