Kim Kardashian showed off her incredible hourglass figure in new snaps shared to her Instagram page late on Wednesday morning.

The 42-year-old reality TV dynamo sizzled as she modeled a new black string bikini from her second SKIMS collection which she has called ‘game-changing swimwear designed for more than the water.’

The Keeping Up With The Kardashians veteran wore her black hair down as she was seen in a gray concrete outdoor shower.

The ex-wife of Kanye West carefully accessorized her swimsuit look as she had on a yellow gold belly chain with a cross pendant.

And the entrepreneur also had on a diamond encrusted chain anklet as she made her best supermodel poses to push the bathing suit that sells for $72.

Kim wore her raven hair down over her bare shoulders and had on nude makeup as the focus was on her very toned figure that included a tiny waistline and impressive abs.

The day before Kardashian was seen exercising very hard in a gym for two hours.

The jet-setter was working out with heavy weights in a gym after returning from a trip to Europe where she modeled fashion.

The star bent her back – and not her legs – while she pulled up a weight that said 80 Iron Grip on one side.

The reality star was flaunting the stunning results of her workout routine as she modeled the same tank top with leggings.

The Skims founder also shared she was working out with her personal trainer, CrushIt app founder Senada Greca, 40, for two hours.

The ex of SNL vet Pete Davidson added she was working off her ‘jet lag’ after being in Europe for the Dolce & Gabbana show and to shoot her series The Kardashians.

‘Nothing like a 2 hr workout w Senada Greca to get my jet lag back on track,’ she wrote over one of the photos.

Finishing off strong is the best feeling ever to check a good workout off of the daily schedule,’ she shared.

Last week she had on a bra top while training with Senada. ‘I mean look at these gainz we’ve been making,’ was written across the Instagram story.

Earlier this month, Senada, posted a photo of the two, praising The Kardashians star for her diligence.

‘The hardest working woman in the room!’ she said.

‘Yes you heard that right! It’s my honour to be training with Kim and to see the person that she truly is: hard working, dedicated, consistent and caring,’ she said.

‘She puts in the work for 2 hours and never complains even when I push her past what she would think are her limits.

‘I know the strength that lays within her, and now, together, we’re working on Kim stepping into her strength.

‘So excited about this journey.’

Kim responded to the praise, writing, ‘I’m so excited for our journey. Stepping into strength with you.’

On Monday Kim took to Instagram to show off her enviable figure and chic ensemble after visiting Dolce & Gabbana in Milan, Italy.

The star shared a carousel of images showing off a cream-colored co-ord made of leather belts that she wore to the opening of the luxury retailer’s flagship store.

While in town for Milan Fashion Week, the SKIMS founder sported a nude buckled cropped motorcycle jacket and a matching miniskirt as she posed in front of her own billboard image.

To match, she also paired the stylish outfit with knee-high, leg warmer-style boots of the same color and material.

In the caption of her post, she wrote: ‘I love you Milan!’ I had to stop by the store to see the collection in stores since it just all arrived!’

‘What a surreal dream come true,’ she added. ‘And thank you all for coming to say hi to me there!’

She continued: ‘I love you Domenico and Stefano for making my dreams come true’.

The entrepreneur also shared four videos at the end of her post that panned around a large group of fans crowing the entire alley to meet and greet Kim herself.
