The Kardashian girls shows off their famous curves for an upcoming issue of Vegas magazine.
Kim Kardashian, 29, Twittered two covers (for the mag's 7th anniversary issue), and asked fans to vote for which one they like better. One shows Kourtney's slim post-baby body in a cut-out one-piece and Kim's cleavage in a low-cut, cut-out suit (Khloe, 25, looks demure in a white suit).

On the second cover, Khloe shows more skin in a cut-out suit, Kim flashes a huge smile (and more cleavage) and Kourtney, 31, rocks a twisted front one-piece.

"Photo shoots like this are so much fun, because it is a great chance to experiment with funkier clothes that I am not used to and wear things I never would have dreamed to put together," she blogged after shooting the November 2008 cover, which was featured on an episode of Keeping Up With the Kardashians.
