Wanton, dissolute (8)
I believe the answer is:
unchaste
I believe this clue is a double definition.
'wanton' is the first definition.
(similar in meaning)
'dissolute' is the second definition.
(I've seen this before)
(Other definitions for unchaste that I've seen before include "very naughty" , "loose" , "fallen" , "Lascivious" , "No longer pure" .)
