WWD reports that Yves Saint Laurent will formally announce the departure of Pilati on Tuesday, and even though it hasn’t yet been confirmed by YSL or the designer himself, Slimane will join the fashion house.

Pilati has been with Yves Saint Laurent since 2004, but his relationship with the house was notoriously contentious. Critical reception of his collections wavered from season to season, and Saint Laurent himself once told a reporter that Pilati’s work was inconsistent: “Some of what he does is good. Some of it is not so good.”

Slimane is stepping in to YSL with no previous experience designing womenswear, but his tenure at Dior Homme, from 2000 to 2007, was critically acclaimed. Slimane was the first menswear designer to be recognized with CFDA’s award for International Designer, and a true golden boy in the eyes of top fashion bigwigs like Karl Lagerfeld.
