Fashionable Christian (4)
I believe the answer is:
dior
'fashionable christian' is the definition.
(fashion designer Christian Dior)
This is the entire clue.
(Other definitions for dior that I've seen before include "Fashion icon, Christian?" , "Fashion house" , "Lift" , "French couturier, creator of the New Look, d. 1957" , "French fashion designer" .)
