Designer Alexander Wang has just launched a denim collection dubbed Denim x Alexander Wang with a very provocative ad campaign. “Once you see it, you can’t stop thinking about it,” said the American success.

Featuring model Anna Ewers oiled up and shot from the waist down in a pair of Alexander Wang jeans pulled halfway down her thighs, her hand positioned to suggest masturbation. Another photograph has her splayed in a chair, wearing nothing but a pair of jeans around her ankles and the “x” from the Denim x Alexander Wang logo strategically positioned across her nipples. “I wanted an image that would provoke,” he said.

The women’s denim line — three cuts in three washes each — will be available for sell as of December 8th in Wang’s New York store and on his U.S. website.

A bit of a denim snob, Wang is as particular about the amount of stretch in the item as he is about the terminology. The Wang 001 is not a “skinny” jean per se, but a “slim” with a high rise to sit at the waist as well as 1 percent stretch for the two indigo washes and 2 percent for the black wash. The Wang 002, or relaxed fit, has zero stretch and is based on a classic men’s fit, but cut for a woman’s body. Then there’s the Wang 003. “We’re not calling them boyfriend jeans,” he said of the boy cut, which rides low and has a wider yet tapered leg. “I hate it when you roll them and your ankle is swimming, so I cut it so you roll it twice and it stays pegged.”

The three washes include variations on light indigo, medium indigo and black. The Stay Black wash has a special reactive potassium dye that resists fading two times longer than most black washes. Rivets are black, as opposed to traditional copper or brass, so they almost disappear into the denim, and there is a single black leather belt loop, a variation on the black leather back pockets that have appeared on his previous jeans for T by Alexander Wang. Everything is manufactured in Los Angeles and prices range from $225 to $295.
