Temporary movement following fashion (9)
I believe the answer is:
makeshift
'temporary' is the definition.
('makeshift' can be similar in meaning to 'temporary')
'movement following fashion' is the wordplay.
'movement' becomes 'shift' (shift is a kind of movement**).
'following' says to put letters next to each other.
'fashion' becomes 'make' (I've seen this in other clues).
'shift' put after 'make' is 'MAKESHIFT'.
(Other definitions for makeshift that I've seen before include "stopgap" , "Cobbled together" , "temporary measure" , "(Acting as) temporary substitute" , "What 11 [SEAMSTRESS] might do" .)
