For Robert Geller, collaboration is part of his brand’s DNA. “My favorite collaborations are the ones where I get to learn about someone else’s craft,” the designer mused. He recalled a Levi’s collaboration that allowed him to deep dive into the world of denim. The learning opportunity, one that he called “absolutely priceless,” led him to launch Robert Geller Denim a few years ago. “It really opened my eyes to what is possible.”

In addition to Levi’s, the designer and CFDA Member collaborated with G-Shock, Garrett Leight and Suicoke, just to name a few, but his seven-year collaboration with Common Projects remains one of his all-time favorites. “We met soon after we had launched our brands and clicked right away,” recalled Geller. “At the end of an after-party for one of my shows, we were the last ones left at the bar and we decided to work together. I feel like the brands align so well, and I really respect what they’ve created.”

Today, Geller is opening up the archives to this seven-year collaboration to the public with a a sample sale from today through March 8. Visit robertgellerstore.com to shop the sale and grab a pair of shoes that once upon a time ago walked the Robert Geller runway.
