Settled differences and put on lipstick etc. (4,2)
I believe the answer is:
made up
'settled' is the definition.
('make up' can be a synonym of 'settle')
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for made up that I've seen before include "Chuffed" , "brought quarrel to an end" , "trying to look attractive?" , "Given slap" , "Supplied" .)
