Trendy model? The opposite (9)

I believe the answer is:

inversion

'the opposite' is the definition.
(I've seen this before)

'trendy model?' is the wordplay.
'trendy' becomes 'in'.
'model?' becomes 'version' (I've seen this before).
'in'+'version'='INVERSION'

(Other definitions for inversion that I've seen before include "upsetting change" , "The opposite of" , "turning around" .)

I've seen this clue in The Times.
