Kim Kardashian looks slimmer than ever as she flaunts her incredible gym-honed figure in black bikini alongside sister Kourtney during family getaway in Costa Rica

The Keeping Up With The Kardashians clan have been sunning themselves in Costa Rica, enjoying some time away from the LA showbiz scene.

And Kim Kardashian, 36, was looking better than ever as she relaxed by the poolside with her family and friends, including sister Kourtney, 37, at their private Villa Manzu.

The reality star - who has since returned to the US - showed off her slender figure in a simple black bikini top, which highlighted her gym-honed, sculpted arms and flat stomach.

Kourtney modelled a white two-piece as she chatted to her sister, showcasing an equally trim figure in her slinky swimwear.

The bikini boasted double strap detailing around the back and barely-there briefs, serving to highlight her shapely posterior.
