Kardashian sisters hunt for plus-size model online

The sisters took to Khloe's blog to announce the search which invites women over the age of 18 to send full-length photos of themselves to the famous sisters, reported Daily Mail.

Kardashian Kurves, the new line, has been created in conjunction with Sears and will feature three styles, each inspired by one of the three sisters.

The chosen model will star in an advertisement for the line, which has not been given a release date as yet.

Khloe outlined the contest's grand prize, a round trip for one to Los Angeles to attend a photo shoot, on her blog.

"It's a venture we're really thrilled about!' The prize also includes one night's accommodation in Los Angeles to ensure their model is in tip-top condition for the campaign's photo shoot," Khloe said.

It was Kim who first announces the line through her Twitter page.

"Our Kardashian Kollection for Sears denim line is officially here!! There are three styles, each named after my sisters and me," she posted.
