Becca McCharen, 31 (far left, with singer-songwriter Tinashe), would like to offer a warning to any future Chromat employees: “Your first week working here, your brain melts from all the math.” This Virginia native approaches her five-year-old label—a hybridized line of engineered swimwear, lingerie, and now sportswear—through the matrices of Excel and CAD, using her architecture background to form carbon-fiber “wings,” patent leather body cages, and intelligent underwear (including, in a partnership with Intel, a self-ventilating mechanized bra that tracks your sweat levels and heart rate). And she’s convinced that the world has seen only the tip of the fashion-tech iceberg: “I’m imagining a day when you can hack the Givenchy collection right off the runway,” she says, “apply it to your body scan, and 3-D print it in the color of your choice.”
