Guess began in 1982 as a book of styles started by Georges, Maurice, Armand, and Paul Marciano. The brothers switched to selling jeans with a light, form-fitting denim and zippers at the ankles. Guess began offering licensed products, including watches, eyewear, and a fragrance line. In 1985, it introduced black-and-white advertisements, which went on to win numerous design awards. Its fashion models have included a number of supermodels, many of whom first achieved prominence via these ad campaigns. In the 1985 Robert Zemeckis movie, Back to the Future, Marty McFly (Michael J Fox) wore Guess's denim clothing, which was reportedly designed specifically for the film.
