The Skinnygirl Cocktails founder, 44, flaunted her fierce physique—the result of a strict, low-calorie vegan diet—at the Floridian hot spot while on vacation with her daughter, Bryn, 4, on Saturday, Feb. 7, and Sunday, Feb. 8.
The reality star, who hosted her own talk show, Bethenny, from 2012 to 2014, first took a dip in a watermelon-hued two-piece, with a string-tied top that revealed her ample cleavage via a deep keyhole cutout.
The next day, Frankel took a stroll on the boardwalk in a navy blue tankini (also with a plunging top), teamed with a bow-adorned white straw hat and shades—the better to shield her skin from the sun. Diamond stud earrings and a tangle of golden bracelets completed her ensemble.
Indeed, the returning Housewife, who split from ex-husband Jason Hoppy last year, looked quite slim in Miami Beach. But to those who have slammed her weight in the past, Frankel told Meredith Vieira on Jan. 13, "I feel like, who cares, they are always going to say something."
She went on to point out that her shape, petite as it may be, is part of her brand. "I do have a brand called Skinnygirl, so I am going to get beaten up for it," Frankel said. "It would be bad if I were overweight and had a brand called Skinnygirl, could you imagine?"
