Kim Kardashian Highlights Billionaire Curves In 'Buttery Soft' Underwear

Kim Kardashian is promoting her SKIMS brand full throttle as she celebrates the company's fifth birthday and enjoys her billionaire status. The 43-year-old, who founded her clothing and shapewear brand in 2019, is fresh from marking five years since the SKIMS debut, and it looks like she's nowhere near done selling stuff. In a share posted to the SKIMS Instagram four days ago, Kim sizzled in a plunging nude bra from her best-selling range, showing off her killer curves while plugging the Fits Everybody collection. Fans called her brand "the best," although one user did complain about struggling to find the right "size."

Scroll for the photo. Facing the camera and posing from a studio, Kim wowed in a sculpted, molded bra that fit her curves perfectly. Displaying her 24-inch waist, the reality star flashed her ample assets in an underwire bra and briefs set, choosing a flesh tone and reminding fans of the lingerie's benefits in a caption.

"Buttery-soft feel and perfect shape without the bulk – there’s a reason this push-up is in everybody’s top drawer," SKIMS began.

Kim, who wore her dark locks down, kept glam with a matte layer of makeup, showing off her defined features while piercing the lens with a direct gaze. Urging fans to shop, SKIMS continued: "@kimkardashian wears the Fits Everybody Push-Up Bra, size 34C, and Fits Everybody Full Brief, size XS, in Clay."

After an alleged mess-up seeing the brand accidentally reveal Kim's dress size earlier this year, SKIMS pulled a 180, choosing to reveal Kim's size in every post she features in.

Kim's milestone was marked by an in-depth feature in the Financial Times's How To Spend It, with the newspaper noting SKIMS' $4 billion valuation. “I handle the visuals, all the ideas, fabrics, fits. I’m the face of this brand," Kim told the outlet.

The FT also noted SKIMS' latest celebrity ambassador, Charli XCX. The British pop star, who joins SKIMS ambassadors including rapper Cardi B and singer Sabrina Carpenter, said: “Kim’s work ethic is hardcore and that’s cool to me, but it’s also very clear to me that she understands her position within culture in a way that so many other people in the public eye just don’t." Chances are, though, Kim's sizzling body is likely playing a role in the sky-high sales of SKIMS, which includes the popular SKIMS Swim.

The above photo, shared in June, brought late-night heat as Kim sizzled in a tube minidress in white. Going strapless and braless outside her vehicle, the mom of four gained over 1.9 Instagram million likes, but responses were mixed as some fans called her product cheap while likening it to budget clothing retailer SHEIN.
