Bethenny Frankel Shows How Underwear Functions 'As A Bikini'

Scroll for the shot. It comes as part of a #nofilter series on Bethenny's Instagram, this as the former Real Housewives star challenges beauty standards by going unfiltered, raw, and real.

The snap showed Bethenny smiling and from a messy car with fancy cream leather seats. The hard-hitter was seen all rock-hard abs and golden tan as she showed off sporty blue briefs with Skinnygirl written on them, plus a plunging and stretchy gray-rib bralette. Shades and a hat completed the beach-appropriate ensemble.

Also going makeup-free and equipped with towels and drinks, Frankel took to her caption, writing: "When you arrive at the beach and realize your underwear can function as a bikini 👙#happyfriday #nofilter @skinnygirlbrand Shapewear Shop on my marketplace ➡️ www.bethenny.com."

Best-known for seeing her Skinnygirl brand turn millions via her beverages, Frankel is now pulling a bit of a Kim Kardashian as she retails shapewear. The star was called "goals" and told she has the "perfect bod" by adoring fans. More after the selfie.

Frankel is fresh from an unfiltered underwear selfie marking her 50 years, one she shared on August 10 as she told fans:

"If I were a 'filterer' I would have gotten rid of my lines and my dark circles, but this is me at 50. #zeroglam #zerofilter."

"I think it's important for young women to know that being flawed is truthful and real, and that filtering yourself into someone fictitious is actually damaging to girls' and women's self esteem. It's courageous and beautiful to be real at any age," she added.

The star stated: "I realize that fake and filtered sells," continuing: "But I'm happy over here with my followers who appreciate the difference. ❤️ #NationalShapewearDay @skinnygirlbrand shapewear."

"This is me at 50," Frankel told her followers, with the post gaining a fire emoji from socialite Paris Hilton, plus a like from media personality Maria Menounos. In 2011, Frankel sold her Skinnygirl cocktail brand to Beam Global for a reported $100 million, retaining the rights to license the brand name for future products.
