Lock feature girl arranged with net (7)
I believe the answer is:
ringlet
'lock feature' is the definition.
'ringlet' can be an answer for 'lock' (both can mean a piece of someone's hair). I'm not certain of the 'feature' bit.
'girl arranged with net' is the wordplay.
'arranged with' indicates anagramming the letters.
'girl' anagrammed with 'net' gives 'RINGLET'.
Can you help me to learn more?
(Other definitions for ringlet that I've seen before include "Curled lock of hair" , "Curl of hair; butterfly" , "Bit of hair" , "hair styling" , "Hair curl, of an Irish dancer perhaps" .)
