About Us GUESS was established in 1981 by the Marciano brothers, who left the south of France in pursuit of the American dream. Inspired by a European influence, the Marcianos redefined denim. One of their initial designs was a stonewashed, slim-fitting jean, the 3-zip Marilyn. Bloomingdale's was the first department store to welcome the brand by ordering two dozen pairs of jeans. They disappeared from the shelves in just hours. This was the beginning of a long success story. GUESS quickly became a symbol of a young, sexy and adventurous lifestyle. Throughout the decades GUESS invited people to dream with its iconic and timeless advertising campaigns that turned unknown faces into famous models. Today GUESS is a truly global lifestyle brand with a full range of denim, apparel and accessories offered in over 100 countries around the world.
