What symbol appears in the logo of the American clothing brand Guess?

A question mark appears in the logo of the American clothing brand Guess.

Guess was founded by the Marciano brothers in 1981 and became associated with fashion jeans, advertising and a distinctive triangle-shaped logo. The question mark is placed inside the triangle and serves as one of the brand’s most recognizable visual elements.

The symbol is not a reference to a particular denim cut or product code. It reflects the brand’s name and creates a visual suggestion of curiosity and mystery. Guess has used variations of its logo across clothing, accessories, stores and advertising, so lettering and layout can differ between products.

The logo question mark is sometimes confused with the brand’s separate product graphics or with the symbols used by other fashion labels. The key identifying feature is the question mark inside the triangular Guess emblem, rather than a star, crown or other decorative mark.
