Top model? (7)
I believe the answer is:
classic
I believe this is a double definition.
'top' is the first definition.
(thesaurus)
'model?' is the second definition.
(I've seen this before)
(Other definitions for classic that I've seen before include "Recognised as excellent" , "Simple, neat and elegant" , "Artistic work of lasting excellence" , "Flat race" , "Important horse race" .)
