These aren't your mom's prom dresses!

Sherri Hill just released their 2013 line of prom gowns -- modeled by Kim Kardashian's younger sisters,  Kendall and Kylie Jenner.

With the two posing in dresses that are either backless or very short, these looks certainly show some skin.

Kendall, 17, and Kylie, 15, have been modeling with the company for some time now -- and have walked in a couple runway shows in Sherri Hill designs.

The partnership is an interesting one, as the two girls are reportedly home schooled and likely won't actually go to a prom unless they go as someone else's date.

What do you think of the dresses? You can see even more of them over at the Sherri Hill website.
