Kim Kardashian Struts around in Tiny Black Bikini on Costa Rica Family Holiday

Kim Kardashian looked like she was on an outdoor runway as she walked along the beach during a family vacation in Costa Rica.

Kim, 38, wore a tiny black bikini that showed off her assets in full under the hot sun. A black wraparound initially hid from her waist down. Photos are found below.

When she got in the water, however, Kim's entire figure was on display. Her tight abs and slender legs got their time to shine, while her chest and behind barely fit into the two-piece.

Kim wore just a simple necklace and a pair of sunglasses for accessorization. According to the Daily Mail, the eyepiece was from an unreleased Carolina Lemke collection.

The reality star had daughter North, in the water with her and the little one seemed to be having a ball of a time. She sported an orange bathing suit and two long colorful braids.

Also present was Kourtney, 40, and ex-boyfriend Scott Disick. Kourtney wore a lovely silver shimmering bikini with a one-shouldered strap for the top.

She and Disick share three children and are known to have one of the more amicable public splits. Disick was photographed chatting with Kim as he sat between the two women on beach chairs.

Despite their ability to get along, the trip was foreshadowed by words from the family monarch Kris Jenner. Inquisitr reported that Jenner spoke to Kourtney about her still possibly having feelings for Disick.

The fact that the actor is currently dating model Sofia Richie also could cause confusion. Still, Disick could just be co-parenting his lovely kids. A source through E! News said he was "hands on" and "helpful."

The Kardashian and Disick kids reportedly brought along some friends, so it seemed to be all hands on deck for the family. According to the source, the children had a ball as they went via boat to a private beach and collected seashells.

While Kim's outfit was smoking hot to match the weather in Costa Rica, over in Japan she was just as sizzling. The mother of four graced the cover of Vogue Japan and her looks were bizarre but fashion-forward.

Actually, she appeared on three of the magazine's covers, as pointed out in her Twitter posts where she shared pictures of the shots. In one, two white hands held onto a red headpiece that covered Kim's head.

In another, her made-up face was surrounded by a light pink satin material. The final was a full-body shot of Kim in a slitted black outfit that showed off her ample cleavage and a belted design at the abdomen.
