Source Unknown is a Dutch womenswear brand founded in Amsterdam in 2020, offering minimalist and sculptural designs that embody a sophisticated interpretation of contemporary Quiet Luxury. Figure-skimming dresses, structured jackets and outerwear, as well as expertly tailored skirts and trousers, are defined by fluid lines and oversized proportions, crafted from leather, wool, cashmere, cotton and selected eco-fibers. True to its name, Source Unknown also features pieces created by independent designers alongside those developed by its in-house creative team. The brand follows a production model based on limited runs and collections released without a strict seasonal calendar, with the aim of reducing waste.
