Kim had her hair pulled back into a uni-braid that looked modern as she had on a full face of nude KKW Beauty makeup.

The bralette looked like a regular bra top with thick straps and a scooped neckline,  and the shorts matched perfectly.

The siren, who has four kids with West, appeared to be standing in the ocean as she made her supermodel poses.

The day before she flaunted her bombshell beach body in a sizzling new set of seaside pictures on Instagram.

The Selfish author  flashed her sculpted midriff as she posed up a storm on some boulders with waves crashing against them.

The mother-of-four was showcasing the new Stretch Rib products from her shapewear line SKIMS, which she launched last year.

Kim put her knockout legs on display and emphasized her derriere in the SKIMS clothing, which she modeled in cream, dark brown and olive green.

She plugged Stretch Rib as ‘a sleek, sport-inspired collection of soft ribbed underwear and loungewear pieces that flatter the body and mold to your curves.’ 

Kim revealed last month her shapewear line SKIMS is looking into helping produce face masks to help make up for the widely reported shortages.

The mother of four explained that ‘we have five factories all in different countries’ while appearing on The View from home at the end of March.

‘And we have been exploring that, of how to make like medical-grade masks, how to make things that would be helpful in the hospitals,’ she said.

‘I’ve been working with our partners in other companies that have donated masks and we’re working with our fragrance company to get sanitizer made.’ 

Earlier Kim announced on Instagram that her shapewear line would be giving $1 million to ‘families affected by COVID-19.’ 

She said on The View that the money will go to Baby2Baby which is ‘helping moms and babies and you know, for the longest time I worked with them donating, you know, diapers and strollers and tons of baby stuff that I’ve had throughout the years.’

Also this week, the high school graduate has been promoting her fragrance collaboration with her mother Kris Jenner in time for Mother’s Day.
