Attractive girl has fortune (6,5)
I believe the answer is:
pretty penny
'fortune' is the definition.
(thesaurus)
'attractive girl' is the wordplay.
'attractive' becomes 'pretty' (I've seen this in another clue).
'girl' becomes 'penny' (woman's name).
'pretty'+'penny'='PRETTY PENNY'
'has' is the link.
(Other definitions for pretty penny that I've seen before include "Large sum of money" , "Large amount (of cost)" , "A tidy sum of money" .)
