Loutish female (7)
I believe the answer is:
ladette
'loutish female' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for ladette that I've seen before include "badly behaved girl" , "Foul-mouthed, beer-swilling girl" , "Girl likely to drink lots" , "Young woman with a loutish lifestyle?" , "lively girl" .)
