Guess Inc. announced the appointment of Andrew Rosen to the role of executive chair of the firm’s recently acquired Rag & Bone brand.

The U.S. fashion company, in partnership with WHP Global, recently completed the acquisition of New York-based fashion brand Rag & Bone, which operates as an independent brand within the Guess portfolio. Los Angeles-based Guess owns all of the Rag & Bone operating assets, and Guess and WHP Global jointly own the Rag & Bone intellectual property, as per the deal.

In his new role, Rosen will provide strategic direction and oversight of the Rag & Bone executive team, to drive the company’s mission forward. In this work, the executive will partner closely with Paul Marciano, Guess co-founder and chief creative officer, and Carlos Alberini, Guess CEO, as well as Yehuda Shmidman, WHP Global chairman and CEO. 

Following an early career at Calvin Klein, Rosen co-founded Theory in 1997 and oversaw the company’s growth as CEO for over 20 years. Today, he remains an active investor and mentor to several American fashion brands, some of which include Alice + Olivia, Veronica Beard and TWP.

“I have been involved with Rag & Bone since 2006. I have always been passionate about our brand and the opportunities that lie ahead. This new relationship now cements that ambition by providing an incredible platform for us to leverage our potential globally,” said Rosen.

“Our executive team and I are excited to embark on this journey with Paul, Carlos, the entire Guess organization, as well as with Yehuda and WHP Global. The passion and opportunities they are bringing to this acquisition are exciting for all of us involved. I am confident that as part of the Guess portfolio, Rag & Bone is well-positioned to build on our success, deliver even greater collections to our customers, and provide our team members with new opportunities for years to come.”

In March, Guess Inc. announced  revenues grew 9% to $891.1 million for the fourth quarter, with the U.S. fashion firm clocking a single-digit uptick in sales for the full-year.
