The Marciano brothers launched the brand extension G by Guess in 2007 as a lower-priced denim line accessible to the 16- to 23-year-old demographicGuessGuess was the first line established by the Marciano brothers. Targeting a slightly older demographic than G by Guess, Guess apparel, as of publication, starts at $40 for short-sleeve T-shirts and goes as high as $300 for high-end dresses.
