Genuine reformation for an inexperienced young woman (7)
I believe the answer is:
ingenue
'an inexperienced young woman' is the definition.
(I've seen this before)
'genuine reformation' is the wordplay.
'reformation' is an anagram indicator.
'genuine' with letters rearranged gives 'INGENUE'.
'for' is the link.
(Other definitions for ingenue that I've seen before include "Naive young actress" , "Unsophisticated young female" , "Artless young woman (on the stage?)" , "Artless innocent young girl on stage" , "Genuine (anag.)" .)
