Sharp look, as redundancies made (4,3)
I believe the answer is:
crew cut
'sharp look' is the definition.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for crew cut that I've seen before include "Distressing" , "Manpower reduced" , "top-level style" , "Closely cropped hair style for men" , "result of ship's economy drive?" .)
