The Duke of Cambridge has officially collaborated with legendary American fashion designer Ralph Lauren, but it’s not what you’d expect. Prince William spent Tuesday morning celebrating the opening and touring of The Ralph Lauren Center for Breast Cancer Research at The Royal Marsden, a newly minted facility within the hospital that’ll specialize in conducting research designed to better treat patients with the disease.

So how did the two household names come together? Like Princess Diana before him, the royal has served as the president of The Royal Marsden NHS Foundation Trust since 2007, the perfect reason for him to join Lauren, who provided a hefty donation for the new building’s inception. For the occasion, William kept it professional and donned a navy blue suit while Lauren followed his traditional fashion M.O. and went the classic route as well.

Once inside, the duo spent time in the endocrinology lab and learned about the process of better understanding tissues and hormone levels, along with other hospital executives. "It was an honor to tour The Ralph Lauren Center for Breast Cancer Research with HRH The Duke of Cambridge today, and to meet some of the special patients being treated there," Lauren told InStyle. "With research happening only two floors away, they too, like other patients in the U.K. and around the world, will be the direct recipients of the new treatments and findings discovered by the commitment of our incredible research team to find a cure for this disease that affects so many."
