A measure of good taste, perhaps (4)
I believe the answer is:
step
'a measure' is the definition.
(step is a kind of measure)
'of good taste perhaps' is the wordplay.
'of' indicates the answer is hidden within the clue.
'STEP' is hidden within 'good taste perhaps'.
(Other definitions for step that I've seen before include "Move a little way" , "Stride" , "Part of a stairway" , "Footprint" , "Put foot on a pest" .)
