SIMPLY DOTTY: Berlin’s KaDeWe was the hot spot for dots Tuesday night. The department store’s atrium was bedecked with circles big and small to celebrate the German launch of Marni’s namesake fragrance. Notoriously shy designer Consuelo Castiglioni, who sent daughter Carolina to tend to local press, did not address the crowd. But she did pause to pose for a photo call. The guests, however, were a little more dotty. Model Franziska Knuppe leapt atop a bench in the form of a bisected bottle of Marni scent to pose for photographer Ellen von Unwerth, for instance.
