It's a success with a woman over here (6)
I believe the answer is:
hither
'over here' is the definition.
(I've seen this before)
'it's a success with a woman' is the wordplay.
'it's a success' becomes 'hit' (hit is a kind of success).
'with' is a charade indicator (letters next to each other).
'a woman' becomes 'her' (her refers to a woman).
'hit'+'her'='HITHER'
(Other definitions for hither that I've seen before include "In this direction" , "Towards this place - not yonder" , "so far" , "Hit her, being towards this place" , "Here (arch)" .)
