Back in vogue, proper depiction of features (1-3)
I believe the answer is:
e-fit
'depiction of features' is the definition.
(image of a suspect created by the police)
'back in vogue proper' is the wordplay.
'back in' suggests the final letters (the 'back' of the word).
'proper' becomes 'fit'.
The final letter of 'vogue' is 'e'.
'e'+'fit'='E-FIT'
(Other definitions for e-fit that I've seen before include "Computer-generated picture for identification" , "Computer-generated form of identikit image" , "image of suspect" , "Digitally generated representation of a face" .)
