Paul Marciano (ca. 1952 in Debdou, Morocco ) is a Moroccan-born American fashion designer of Jewish descent and co-founder of Guess? Inc. He is the mastermind behind the Guess? image and his sensual black-and-white advertisements have won numerous Clio awards. Initially run by all four Marciano brothers (Paul, Armand, Maurice and Georges), today the company and its extension lines, Marciano and G by Guess, are handled only by Paul and Maurice. He is also a large benefactor to one of the larger Sephardic synagogues in Los Angeles, Em Habanim.
