Denim Jeans Marty's jeans are by Georges Marciano for Guess Jeans. Similarly to the shirt and vest, locating an original is expensive and difficult. Fortunately, the jeans, while distinct in the detailing, are also general enough to pass for other jeans. They're labeled "Made in America" on the back pocket. In Back to the Future: Part II, when Marty travels through time, he wears different clothes than in the first movie. His denim jacket is red instead of black and white, and his pants are blue instead of gray. However, his shoes remain the same as in the original film. In addition to being named after a car made by Chevrolet, Marty's jacket may be referencing the fact that it is a brand owned by General Motors. In 2015, they will no longer be made in America. As for the location of production, we can only assume that it has been moved overseas. His pants could be referencing American fashion designer denims, which became popular in the 1950s. These pants usually have multiple pockets including one on the backside. In conclusion, Marty wears generic black-and-white-striped jeans.
