LONDON — The British designer Kim Jones was confirmed as the new artistic director of Dior Homme on Monday, two months after he stepped down as artistic director of men’s wear at Louis Vuitton. He will replace Kris Van Assche, who was in the role 11 years.

The creative reshuffling and the hiring of Mr. Jones, who will start April 1, are the first major strategic decisions by Pietro Beccari, chief executive of Christian Dior Couture, who joined the brand from Fendi in November. The news will probably heighten speculation about the future of Maria Grazia Chiuri, the fashion house’s artistic director of women’s wear, whose tenure has received mixed reviews. And it comes just days after another major fashion house, Nina Ricci, said its creative director of three years, Guillaume Henry, was stepping down.

The announcement on Monday ends feverish speculation about Mr. Jones’s next move. The news of his appointment came minutes after LVMH Moët Hennessy Louis Vuitton, the French luxury conglomerate that owns both Christian Dior and Louis Vuitton, said that Mr. Van Assche would be leaving Dior. Mr. Van Assche will, however, remain in the LVMH group, a statement said, in a role that has yet to be announced.

“I am delighted to welcome Kim Jones at Dior Homme,” Mr. Beccari said in a statement, adding that Mr. Jones would “create an elegant men’s wardrobe both classic and anchored in contemporary culture.”
