Goes for semi-nude roles (7)
I believe the answer is:
departs
'goes' is the definition.
('depart' can be a synonym of 'go')
'semi-nude roles' is the wordplay.
'semi nude' becomes 'de' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'roles' becomes 'parts' ('part' can be a synonym of 'role').
'de'+'parts'='DEPARTS'
'for' is the link.
Can you help me to learn more?
(Other definitions for departs that I've seen before include "Goes, leaves" , "Goes away" , "Quits" , "Does runner" .)
