Melissa Battifarano was once known as "Rihanna's right hand." That's how Vogue has described her work helping to establish Fenty Corp. as a fashion player with Rihanna. On the episode, Melissa unpacks how she created Fenty X Puma and Savage X Fenty with the diamond-drenched performer. She talks about how rising through the ranks of labels like Sean John, Champion and Tory Sport, she worked with the teams that merged athletic garb with fashion and created athleisure and sport luxury.

The downtown New York designer shares how she now balances her work producing Tony 1923, her own luxury sportswear line inspired by her late father, with a new role ideating Diesel's first activewear line under the brand's creative director, Glenn Martens.
