Perfect female, unruly (8)
I believe the answer is:
flawless
'perfect' is the definition.
('flawless' can be similar in meaning to 'perfect')
'female unruly' is the wordplay.
'female' becomes 'f' (abbreviation).
'unruly' becomes 'lawless' (I've seen this before).
'f'+'lawless'='FLAWLESS'
(Other definitions for flawless that I've seen before include "Without blemish or imperfection" , "Unblemished" , "Without blemish or fault" , "Without blemish, perfect" , "Immaculate" .)
