Twice make for poser (7,5)
I believe the answer is:
fashion model
'twice make for poser' is the definition.
I can't tell whether this defines the answer.
'make for poser' is the wordplay.
'make' becomes 'fashion' (both can mean manufacture).
'for' is a charade indicator (letters next to each other).
'poser' becomes 'model' (e.g. a model for an artist - someone who poses).
'fashion'+'model'='FASHION MODEL'
Can you help me to learn more?
(Another definition for fashion model that I've seen is " Catwalk mannequin".)
