Well-formed plays he gets rewritten (7)
I believe the answer is:
shapely
'well-formed' is the definition.
(thesaurus)
'plays he gets rewritten' is the wordplay.
'gets rewritten' indicates anagramming the letters.
'plays'+'he'='playshe'
'playshe' with letters rearranged gives 'SHAPELY'.
(Other definitions for shapely that I've seen before include "Looking good?" , "Curvaceous" , "Pleasingly formed" , "Attractively proportioned" , "Well-proportioned" .)
