Outlaw born with sex appeal (6)
I believe the answer is:
bandit
'outlaw' is the definition.
(I've seen this before)
'born with sex appeal' is the wordplay.
'born' becomes 'b'.
'with' becomes 'and' (I've seen this before).
'sex appeal' becomes 'it'.
'b'+'and'+'it'='BANDIT'
(Other definitions for bandit that I've seen before include "Crook" , "Outlawed robber" , "Thief" , "Highwayman" , "hood" .)
