Kardashian sisters, Khloe Kardashian, Kourtney Kardashian and Kim Kardashian, have graced a new advertisement for the Kardashian endorsed swimwear line, Beach Bunnies. In the ad, Khloe and Kourtney don black swimsuits, while Kim wears snake-pattern bikini.

Khloe poses for the Beach Bunnies ad in black halter backless one-piece swimsuit with lighter-colored string details. Beside boasting her back, Khloe's sexy stomach still can be seen in the swimsuit. Kourtney, in the meantime, sports black skimpy halter bikini matched with big bracelets. Meanwhile, Kim doesn't go black like her sisters do. She opts snake-pattern halter bikini with black strap details in the undies.

Although Kourtney, Khloe and Kim look attractive in their slinky swim-wears, some sites suggested that the sisters had their bodies photo-shopped for the ad. Khloe, who is much taller than her sisters, appears only an inch or so taller than them.

Khloe has previously said that she loves "being tall." She said, "I embrace my height and wear the tallest of shoes. I personally think my sisters are so cute and petite but they always say they wish they had legs like mine."
