Guess is the fashion brand founded in 1981 by the Marciano brothers that makes Guess sunglasses.
The Marciano brothers—Georges, Armand, Paul, and Maurice—founded Guess in 1981. The company became especially associated with denim, advertising campaigns, and a youthful American fashion image, later adding accessories such as watches, handbags, footwear, and sunglasses.
Guess is sometimes confused with similarly styled denim and lifestyle brands, including Diesel and Tommy Hilfiger. Its defining historical clue is the Marciano family and the 1981 founding date.
Guess eyewear is part of the brand’s broader accessories business. The fashion label’s name is written in capital letters in much of its branding, but the canonical company name is Guess.
