Strauss of denim (4)
I believe the answer is:
levi
'strauss of denim' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for levi that I've seen before include "Matthew (NT)" , "Hebrew patriarch - Italian writer" , "Matthew the apostle" , "Primo --, Italian writer and chemist" , "Priest of the ancient Jewish Church" .)
