Ask for, with charm (6)
I believe the answer is:
appeal
I believe this clue is a double definition.
'ask for' is the first definition.
(appealing is a kind of asking for)
'charm' is the second definition.
('appeal' can be a synonym of 'charm')
'with' is the link.
(Other definitions for appeal that I've seen before include "Attraction - legal process" , "Supplication to take a higher court" , "Allure, attraction" , "attract one's interest" , "fetching" .)
