PARIS--Lacroix is back, ladies and gentlemen--sans Christian, alas. When the house closed in 2009 after going through severe financial trouble, we mourned its baroque dementia. But today, Sacha Walkhoff, his assistant of 17 years, is in charge. “We are going to run the house very differently than we once did,” said Walkhoff, “we are currently developing lots of licenses, and are starting by relaunching Lacroix homme. We’ll wait a little longer to restart women.” The line, shown through a presentation at the Maria Luisa boutique themed around "migrating boys," was for elegant globetrotters: Suits with flowery seams and lining, spurts of color and button badges. “Lacroix, Chapter Two” as Walkhoff put it. Bernhard Willhelm did his usual nutty number: the Solomon de Rotschild private mansion in Paris was taken over and transformed into a gigantic performance that looked like Willy Wonka going off to the jungle.
