Focus on “just the product,” the Dutch denim couture label G-Star commands us. Since 1989, G-Star has produced a reliably cutting-edge clothing collection featuring untreated, raw denim jeans, fitted leather jackets and blazers, sleek organic cotton T-shirts and button-down shirts, and minimalist dresses. One of the leaders in perfecting three-dimensional denim, G-Star also turns to the past for some of its fabric techniques — for example, by using vintage looms to create its Red Listing denim. In addition to jeans, G-Star produces the Sports Original line of puffer parkas and arena jackets and footwear ranging from men’s work boots to women’s wedge sandals and ankle booties.
