Kim isn't the only Kardashian who knows how to show off her kurves.

The reality star's little sis Khloe hung out with a pal in Miami Wednesday, where she rocked a sexy, strapless black-and-lace frock (from the Kardashians' Sears Kardashian Kollection line) which highlighted her long legs and hourglass figure.

Khloe, 28, is reportedly in Miami for a photo shoot with U.K.-based women's store, Dorothy Perkins. (The Kardashian women are expanding their fashion empire, creating an exclusive clothing line for the European brand.)

In addition to her fashion designing duties, Lamar Odom's love recently landed an exciting new hosting gig: as Us Weekly confirmed October 2, Khloe (along with Mario Lopez) will serve as a host on the new season of The X Factor.

A show source explained to Us that Khloe had made an impression on Simon Cowell and other FOX network executives during her meetings with the show's creators. "Simon liked her spunky personality!" the insider revealed.
