The 19-year-old model was shot by photographer David Bellemere for the campaign, which took place in her hometown Malibu.
“Going on 15 years as a Guess Girl, this may be my favorite campaign yet. The collection is so effortless to wear, and fits perfectly in any summer environment,” Gigi shared in a statement. “I couldn’t think of a better place to shoot the campaign then where we did – on the beaches of my hometown in Malibu! So fitting.”
