Kim Kardashian flaunts her hour glass figure in a navy-blue two-piece from her Kardashian Kollection- the fashion line she started with her sisters Khloe and Kourtney.Kim took to Twitter to promote the shoot and posted the snap with the caption: "Kourt, Khloe and I put on our favorite bikinis for our new #KardashianKollection swimwear shoot!"No doubt the curvy beauty looks ten on ten, however, her waistline seems unusually thin. Is this another case of airbrushing?While Khloe (on Kim's right) is seen wearing a lace bikini with a sheer kaftan over the top, Kourtney dons a strapless bikini. Kourtney, who is preganant with her second child, shows no sign of a baby bump. Photoshop can certainly work wonders!The shoot with the three beauties is done with a clouds and sea backdrop.Kardashian Kollection Intimates line was launched two weeks back. During the launch, Kim had said: "My sisters and I are excited to reveal our new ad for our Kardashian Kollection Intimates! The intimates line is so gorgeous, comfortable and feminine and we are very proud of the line."Earlier this month, the Kardashian sisters went topless in a racy photoshoot to promote their denim line for Sears.
