Baffling question for a model (5)

I believe the answer is:

poser

I believe this is a double definition.

'baffling question' is the first definition.
(I've seen this in another clue)

'for a model' is the second definition.
('poser' can be a synonym of 'model')

(Other definitions for poser that I've seen before include "Particularly baffling problem" , "Someone behaving so as to be noticed" , "This person's affected" , "Puzzling problem" , "Hard question" .)

I've seen this clue in The Globe and Mail.
