What's in that Kardashian jean pool? Funny you should ask.

After rounding up the fam for a not-at-all-awkward lingerie shoot, Kourtney, Kim and Khloe are teaming up for a new campaign in support of their Kardashian Kollection Denim range for Sears.

Available for $68 a pair, each jean is named after a sibling with styles and descriptions to match their respective body types.

For Kim—who, like her sisters, sports a white button-down shirt and flowing mane—that means a "sexy curvy low-rise straight leg" jean that shows off that famous backside.

The Khloe, meanwhile, references the youngest Kardashian's height with its "tall curvy high-rise boot cut," while Kourtney (photographed pre-pregnancy?) models a "slim-fit low-rise skinny leg" version.

Think they made a "mom jean" for Kris Jenner?
