Christian of fashion (4)
I believe the answer is:
dior
'christian of fashion' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dior that I've seen before include "Fashion house" , "Christian --, French clothes designer" , "French couturier, creator of the New Look in 1947" , "Lift" , "French couturier, creator of the New Look, d. 1957" .)
