Sloshed looker in black and white (3-4)
I believe the answer is:
pie-eyed
'sloshed' is the definition.
(I know that sloshed can be written as pie-eyed)
'looker in black and white' is the wordplay.
'looker' becomes 'eye' (I've seen this in another clue).
'in' indicates putting letters inside.
'black and white' becomes 'pied' (I've seen this before).
'eye' put into 'pied' is 'PIE-EYED'.
(Other definitions for pie-eyed that I've seen before include "Blotto" , "Very drunk (colloq.)" .)
