Avoid humiliation, though cute cafe vase is knocked over inside (4,4)
I believe the answer is:
save face
'avoid humiliation' is the definition.
(I've seen this in another clue)
'cute cafe vase is knocked over inside' is the wordplay.
'inside' says the answer is hidden in the clue.
'is knocked over' is a reversal indicator.
'ecafevas' is hidden within 'cute cafe vase'.
'ecafevas' written backwards gives 'SAVE FACE'.
'though' is the link.
(Other definitions for save face that I've seen before include "Avoid humiliation, retain standing" , "Preserve dignity or reputation" , "Maintain one's dignity" .)
