Apparently Mr. Shiffman, who was appointed Calvin Klein’s chief executive in 2014, agreed, and in April, Mr. Costa and Mr. Zucchelli left the brand, making way for Mr. Simons, who reportedly had a noncompete agreement with Dior that prevented him from joining Calvin Klein until this month. Calvin Klein had sales of $8.2 billion in 2015 and has publicly declared its ambitions to grow to $10 billion.
Mr. Simons will “oversee all aspects of design, global marketing and communications, and visual creative services,” the company said. And his long-term collaborator, Pieter Mulier, was named Calvin Klein’s creative director.
The first test will come next year, when Mr. Simons presents his men’s and women’s fall collections for Calvin Klein.
