A representative of the label in Paris said Thursday that "she leaves her label, and the label of Ann Demeulemeester will continue without Ann Demeulemeester for many years."
Demeulemeester has been designing collections since 1987 and said in a handwritten note accompanying her departure that she leaves "a happy and fulfilled person, ready to create new challenges in life."
Antwerp Six were avant-garde designers who helped reshaped Paris fashion landscape in the 1980s-1990s. Demeulemeester was noted for experimenting with cut and drape, turning bourgeois outfits into something slouchy, dark and minimal.
"I always followed my own path," she wrote.
She did not specify her future plans.
