Some finesse? Let's attempt to turn vulgar (9)
I believe the answer is:
tasteless
'vulgar' is the definition.
('tasteless' can be similar in meaning to 'vulgar')
'some finesse? let's attempt to turn' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'to turn' is a reversal indicator.
'sseletsat' is hidden in the letters of 'finesse lets attempt'.
'sseletsat' reversed gives 'TASTELESS'.
(Other definitions for tasteless that I've seen before include "Vapid" , "Lacking flavour or ability to appreciate the beautiful" , "Bland; offensive" , "Lacking flavour or aesthetic appreciation" , "improper" .)
