Calvin Klein's latest lingerie campaign declares that the skivvies seen on Lara Stone are "designed to make a woman look even sexier than when naked." And the suggestive slogan doesn't surprise us: The brand has never shied away from using sex to sell.

"You want to know what comes between me and my Calvins? Nothing," revealed a 15-year-old Brooke Shields in the famous rife-with-innuendo 1981 TV spot. Though the ads caused the designer's revenues to jump by 300 percent in 90 days, according to Newsweek, it invited protest from feminists like Gloria Steinem (Klein later instructed Steinem to "F--ck off" in a Playboy interview).

And Calvin's penchant for sex appeal has continued throughout recent years. In 2008, an oiled-up Eva Mendes appeared topless in a campaign for the fragrance "Secret Obsession" that was nixed by network execs. And in 2009, the brand stopped traffic with its erotic tableau shot by Steven Meisel, which WWD reports was banned even by late-night TV.

Of course, Klein isn't the only designer to court controversy. When critics accused Dolce & Gabbana of glamorizing gang rape in a 2007 campaign, the designers were forced to pull the offending ad. Their response? "We were looking to re-create a game of seduction in the campaign and highlight the beauty of our collections," Reuters reported at the time.

Diesel's "Be Stupid" campaign, which saw scantily clad models doing just that, took a lot of heat. As did Tom Ford and Terry Richardson for this memorable crotch shot. Marc Jacobs himself stripped to promote his Bang fragrance last summer. And provocateur Dov Charney's revealing ads for American Apparel have long been deemed exploitative.

What do you think of racy fashion ads -- perfectly steamy or just too sleazy?

Warning: Some of these ads are extremely graphic. And check out who else isn't afraid of risqué photo shoots (with Kate Moss, natch.)
