Fashion designer Christian (4)
I believe the answer is:
dior
'fashion designer christian' 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 "French couturier, who created the New Look" , "Christian ..., couturier" , "Christian --, French clothes designer" , "Fashion icon, Christian?" , "Fashion designer Christian, famous for his 1947 New Look" .)
