Calvin Klein, famous for using waif models like Kate Moss in its advertising, is making headlines with size 10 model Myla Dalbesio featured in its newest ad campaign, reports USA TODAY.

Calvin Klein does not consider Dalbesio a plus-size model, despite reports to the contrary.

"It's kind of confusing because I'm a bigger girl," Dalbesio told Elle.com. "I'm not the biggest girl on the market, but I'm definitely bigger than all the other girls (Calvin Klein) has ever worked with, so that is really intimidating."

Dalbesio, 27, says she is between plus and a "straight size" in the Elle.com interview.

"True body diversity doesn't mean only sizes 0's and 2's then jumping to size 16 and up. There is a middle ground," the model told Elle.com.

The frenzy of conversation on social media about Calvin Klein's newest model has been mixed. Some people are pleased the designer is incorporating diverse body shapes into its advertising while others were unhappy about size 10 being touted as a plus-size.

Calvin Klein described to Elle.com its new Perfectly Fit line as a way "to celebrate and cater to the needs of different women, and these images are intended to communicate that our new line is more inclusive and available in several silhouettes in an extensive range of sizes."

The buzz about Calvin Klein's curvier model is part of a much bigger discussion about the unrealistic imagery used in the media and fashion world.

Victoria's Secret recently faced sharp criticism for the tagline "The perfect 'body'" used in its "Body" line of bras advertising. A Change.org petition deemed the marketing "irresponsible" and urged people to tweet about it. The social media backlash was significant enough that Victoria's Secret changed the tagline.

Celebrities have challenged the unrealistic images of pop culture and advertising. In August, actress Keira Knightley agreed to go topless for an Interview magazine photo shoot if her body was not Photoshopped.

"It does feel important to say it really doesn't matter what shape you are," Knightley told The (U.K.) Times.
