Claudia Schiffer for Guess 30th Anniversary Ad Campaign

Claudia Schiffer looks sexier than ever as she poses for the new Guess 30th Anniversary Ad Campaign photographed by Ellen Von Unwerth. The famous brand celebrates three decades of sexiness and style releasing a 15-piece capsule collection inspired by iconic Guess girls.

Claudia Schiffer fronts the latest Guess 30th anniversary ad campaign photographed by Ellen Von Unwerth in Sorrento in Italy. The 41-year-old supermodel goes back to her roots after posing for the famous brand in six Guess campaigns from 1989 to 1991. The renowned label revisits one of its iconic campaigns and celebrates its "30 sexy years!" with a stunning selection of black-and-white photographs as the ones taken by von Unwerth back in 1989. And we must admit that Schiffer is looking as amazing as ever 23 years later.

"Guess will always have a soft spot in my heart, and I'm excited that 23 years later we can still work together so successfully," Schiffer told Women's Wear Daily. "Shooting the Guess 30th anniversary campaign was like going back in time. It brought back so many great memories and has been a lot of fun working together again with Ellen and Paul."

Paul Marciano, chief executive officer and creative director of Guess, is also extremely thrilled about the brand's collaboration with Schiffer. "She was a turning point of Guess, she was a turning point of Ellen’s career, Guess was a turning point of a life for Claudia," Marciano told WWD. The campaign image "made her career in my view, and that made Guess a different company. Everybody talked about the Guess Girl," he said.

The new Guess 30th Anniversary Collection is inspired by the brand's pieces worn by famous Guess girls over the past three decades. The 15-piece collection will feature pieces inspired by Claudia, but also by Laetitia Casta, Naomi Campbell, Bridget Hall, Drew Barrymore and Estelle Lefébure. There are wide-neck T-shirts printed with bedazzled images of Line Gost and Anna Nicole Smith, a sheer leopard-print blouse, jeans with a cut-off waistband originally modelled by Adriana Lima, a sleeveless black-and-white gingham top worn by Eva Herzigova, and the three-zipper Marilyn jeans that launched the brand.

You can also take a peek at the advertising campaign video featuring gorgeous Claudia Schiffer, developed under the creative direction of Paul Marciano, CEO and Creative Director of GUESS Inc., and directed and shot by photographer and longtime GUESS collaborator, Ellen von Unwerth. Paul and Ellen also teamed up in 1989 for Claudia's first GUESS campaign and "the three have reunited now for the print and video campaign to celebrate this special milestone for the brand."

This special capsule collection is set to be launched worldwide on April 24th in Guess stores and on a new website, www.guess1981.com, which was created especially for the anniversary. The goodies, drawing their inspiration from the pieces featured in archived GUESS images yet updated with a modern twist, will be priced from $39 to $138.
