Jaunty; dissolute (6)
I believe the answer is:
rakish
I believe this is a double definition.
'jaunty' is the first definition.
(I know that jaunty can be written as rakish)
'dissolute' is the second definition.
(I've seen this in another clue)
(Other definitions for rakish that I've seen before include "Dapper" , "Marked by unconventionality or disreputableness" , "abandoned" , "Dashing and slightly disreputable" , "Profligate" .)
