The 39 year-old English supermodel poses both in and out of a white swimsuit to showcase her artificial glow from St Tropez products in the company's first ever global advertising campaign.
"I’ve been using the products since they started," Moss explains in a release announcing her appointment as the face of the brand. "I always feel more confident with a St.Tropez tan," she added.
Michelle Feeney, CEO of PZ Cussons Beauty, owners of St.Tropez, said: "Kate epitomises St.Tropez’s naturally glamorous approach to self-tanning and is a long-time advocate of the brand".
"Kate’s fashion icon status is important to us but now her growing number of beauty campaigns proves that her appeal as a beauty icon resonates with confident women across all age groups globally. Not only is she beautiful but she has this amazing attitude. St.Tropez is about confidence."
Giving advice on how to achieve Moss' enviable tan in the shots, Nichola Joss, St. Tropez Global Tanning and Skin-Finishing Expert, says: "To achieve Kate’s pool-side bronze for the shoot, the St. Tropez Self Tan Bronzing Mousse applied with a St.Tropez Applicator Mitt gives a natural-looking, streak-free result with a flawless finish".
"St.Tropez Powder Bronzer perfects the look with a beautiful contoured effect and enhances the natural shape of Kate’s body."
