Display disreputable author's trousers (7)
I believe the answer is:
tableau
'display' is the definition.
(thesaurus)
'disreputable author's trousers' is the wordplay.
'trousers' indicates a hidden word (trouser can mean to steal or take).
'TABLEAU' is hidden within 'disreputable authors'.
(Other definitions for tableau that I've seen before include "Painting - spectacle" , "Scene of still figures" , "picture that's striking" , "Motionless figures representing a scene" , "Group of people arranged as for a painting say" .)
