In 1980, Oakland ballet dancers David Lee and Tricia Kaye made knit footless tights that could be folded over at the waist, starting a revolution in dancewear and workout wear. In 1983, the brand moved to New York and regularly sold their products to leading dancers in the New York City Ballet and the American Ballet Theatre. In 1990, they began using computerized knitting machines, allowing the line to introduce more styles and develop new yarns. In 2019, Kd launched a kickstarter campaign to bring Vegetable Cashmere™ to market, after years of development, testing, and refining.
