Kim Kardashian has followed up her Instagram "unveiling" with a more tasteful -- but every bit as sexy -- series of photos with her sisters Kourtney and Khloe taken by renowned photographer Terry Richardson.

In the shots promoting their Kardashian Kollection line for the U.K.'s Lipsy, the curvy 32-year-old socialite glams it up in a shimmery black mini-skirt, and a lacy red dress.

It's clear her regimen of the Atkins diet and a grueling exercise regimen since the June birth of her daughter North have paid off in a big way, as it was just months ago bloggers made her the butt of their jokes chronicling her figure and fashions during her pregnancy.
