For its Fall '09 campaign, Guess takes the brand back to its roots and focuses on its denim collection. The ad features Norwegian model Siri Tollerod decked out in the brand's jeanious offerings. The side ponytail, studs, ripped tee, and denim vest all point to the '80s, and I'm kinda loving it. Check out how the gritty background and the couple making out behind Siri feed into the grungy vibe. Side note: my first pair of Guess jeans, circa 1993, had red and black vertical stripes with zippers on the side — wow. Are you loving Guess's denim revival campaign?
