Urge charming female to go topless (4)
I believe the answer is:
itch
'urge' is the definition.
(I've seen this in another clue)
'charming female to go topless' is the wordplay.
'charming female' becomes 'witch' (I've seen this before).
'to go topless' means to remove the first letter.
'witch' with its initial letter taken away is 'ITCH'.
(Other definitions for itch that I've seen before include "It needs to be scratched" , "Constant desire" , "longing for something" , "Uncomfortable feeling" , "Seven-yearly desire" .)
