French fashion brand that collaborated with Amoako Boafo (4)
I believe the answer is:
dior
(Other definitions for dior that I've seen before include "Lift" , "Christian ..., couturier" , "Christian --, French clothes designer" , "French couturier, creator of the New Look, d. 1957" , "French couturier, creator of the New Look in 1947" .)
