Kering may be on a cost-cutting drive under new chief executive officer Luca de Meo, but you wouldn’t know it from the bombastic show Saint Laurent staged on Monday night. In a rare appearance, Madonna arrived fashionably late with her daughter Lourdes Leon and boyfriend Akeem Morris. He will also appear in Lena Dunham’s rom-com “Good Sex,” due to come out on Netflix next year. Will there be good sex? After the show, Madonna lingered to warmly embrace Gaultier, who famously designed her cone bra for the 1990 Blonde Ambition tour.
