American-based Guess was founded by Moroccan brothers Georges, Armand, Paul and Maurice Marciano in 1981. The brand started out as a largely denim-based company, with its first product being a three-zipper style of jeans. American department store Bloomingdale’s agreed to stock this new style of stonewashed denim, and Guess catapulted to success when its designs sold out almost instantly. The brand has now expanded into an international fashion powerhouse selling everything from watches and footwear to jeans, t-shirts and more. Your go-to brand for youthful, casual separates with a sexy edge.
