Back in Her Bikini! Kim Kardashian Shows Off Her Stunning Figure As She Sunbathes in Tiny Two Piece

On Saturday afternoon the Keeping Up With The Kardashians beauty showed off her perfect curves in a tiny flesh-toned two piece as she relaxed by a swimming pool while on vacation in sunny Costa Rica.

Also with the 36-year-old wife of Kanye West was sister Khloe, 32, and assistant Stephanie Sheppard.

The mother-of-two wore her long raven locks down before going for a dip with her pals.

The pinup had an awful 2016 with her Paris robbery and the mental breakdown of her husband West, causing her to take a break from the public eye.

But she certainly has not been binging on fast food and sweets to deal with the stress.

Kim actually appears to be in the best shape of her life. She has slimmed down remarkably well since welcoming her son Saint into the world in December 2015.

Not only were her arms toned, but the E! queen showed off muscles in her midsection and had very shapely legs.

The I Am Cait guest star was seen laying on a green lounger, arranging her towel and floating in the pool.

Khloe stayed more covered up in a maroon one piece.

This sighting comes on the same day that Kim said in a Snapchat video that she works out an hour every day.

'So I never Snapchat my workouts and I don't know why. I'm just not Kourtney and Khloe. But I work out but it's like, if I don't snap it, then it's as if it never happened. But I work out every single day for over an hour,' she said.

The star has said she is still on the Atkins Diet.

Kim also shared photos of her with a bunny filter that had fuzzy ears and whiskers with a pink nose. Daughter North and son Saint were also in the clips.

The star seemed to be enjoying her animal filter as she kept the camera on her famous mug for quite some time.

The family looked to be staying in a home. The colors were a neutrals with a white sofa and dark beige carpeting as well as a wood coffee table.

Also there was sister Khloe, who wore a white tank top and also had a filter. She was playing with Kourtney's son Reign. Reign wore a grey top and gold chain like father Scott Disick.

On Friday night the family went out for dinner at Ostra.

The star's white crop bra top looked custom made.

It not only showed off plenty of the reality maven's cleavage, but it also flashed her stomach muscles, which are very impressive considering she welcomed son Saint into the world just over a year ago.

Kim added black slacks and heels to her eye-popping number.
