'This is me at 50': Bethenny Frankel wows while proudly posting a filter-free selfie in her bra and underwear

Bethenny Frankel oozed confidence in a new Instagram on Tuesday.

The reality star proudly went filter-free as she snapped a fresh-faced underwear selfie to mark 'National Shapewear Day'.

Standing in her bedroom in a black sports bra and red briefs, she wrote: 'This is me at 50.'

Bethenny proved her own best advertisement in the stripped back snap.

The waistband of her underwear was branded Skinnygirl, which is Frankel‘s own company.

Bethenny‘s bare legs and flat midsection were on full display in the mirror selfie.  

She wore a delicate silver pendant and a ring. 

Her brown hair was down and she puckered her lips ever so slightly.

'If I were a "filterer" I would have gotten rid of my lines and my dark circles, but this is me at 50,' the former Real Housewife of New York captioned the snap, adding the hashtags #zeroglam and #zerofilter.

'Why do I mention this all the time? Because 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,' she continued. 'It’s courageous and beautiful to be real at any age.

'I realize that fake and filtered sells, but I’m happy over here with my followers who appreciate the difference.❤️' BF concluded, adding '#NationalShapewearDay @skinnygirlbrand shapewear'

And while her intention was pure, Bethenny’s train of thought in the caption was seemingly at odds with the name of her lifestyle brand Skinnygirl, which by definition would alienate any potential customer who is not, in fact, skinny. 

The beauty, meanwhile, kept the selfie parade coming on Tuesday, adding a few more selfie snaps and videos, including one fresh out of the water and wrapped in a beach towel.

The TV star and entrepreneur also included a video in which she was seen dancing in a market, wearing a denim jumpsuit that also came from her brand.
