First name in denim
I believe the answer is:
levi
'first name in 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 "The Strauss who first patented blue jeans" , "Primo --, Italian writer and chemist" , "OT character" , "Biblical priest" , "Hebrew patriarch - Italian writer" .)
