Play about fashion (8)
I believe the answer is:
recreate
'play' is the definition.
(I know that play can be written as recreate)
'about fashion' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'fashion' becomes 'create' (I've seen this in another clue).
're'+'create'='RECREATE'
(Other definitions for recreate that I've seen before include "Bring back" , "design again" , "Produce again" .)
