Lottie Moss, the teen-age sister of model icon Kate Moss stars in a new jeans campaign for controversial designer Calvin Klein that skirts the line on exploiting underage sexuality to sell a fashion line.

The brand is infamous for running sexually provocative ads over the years featuring young people to tout its brands.

In 1980, then-15-year-old Brooke Shields modeled the brand’s jeans with the provocative tagline: “Do you know what comes between me and my Calvins? Nothing.”

Lottie, all of 16, appears in one photo wearing a denim shirt without a bra.

In other photos, she appears in sexually charged poses.

In one, she wears short-shorts and a sleeveless tee-shirt that exposes her midriff. Her hips are cocked seductively, evoking images of Jodie Foster’s portrayal of a teen hooker in the 1976 movie, “Taxi Driver.”

The Council of Fashion Designers of America (CFDA), a fashion industry oversight group adopted voluntary guidelines in 2007 calling on designers to stop employing models under the age of 15.

Under the CFDA’s guidelines, Lottie would be allowed to walk in runway shows and pose for editorial campaigns because she turned 16 in January.

But U.S. pornography laws are another matter. Because Moss is under 18, Calvin Klein could be skirting the line by photographing her in sexually suggestive poses.

Under federal law, “the legal definition of sexually explicit conduct does not require that an image depict a child engaging in sexual activity,” according to the U.S. Department of Justice’s legal guidelines.

“A picture of a naked child may constitute illegal child pornography if it is sufficiently sexually suggestive,” according to the guidelines.

The fashon brand could also be prosecuted under state child pornography laws, which might be stricter.

While the Calvin Klein images are sexual, they are not “sexually explicit” and Moss does not appear nude in any photos.

Still, the sexualization of teens has been a major issue among parents’ and feminist groups.
