Bethenny Frankel poses in stylish swimsuits while in Italy with fiancé Paul Bernon

Bethenny Frankel dives into summer by posing in a set of swimsuits during her holiday in Italy.

On Friday, the Skinnygirl founder took to her Instagram page and shared multiple photos and a video of herself enjoying the outdoors in a variety of swimsuits that included both bikinis and maillots, more commonly known as one-piece suits.

And while Frankel didn’t share the names of the designers behind each piece, the sunny show comes about four weeks after she launched Bethenny Swimwear, her first collection of swimsuits with HSN.

In the post, The Real Housewives Of New York City alum modeled four different colored suits that came in a variety of styles.

“50 Shades of swim #summerinitaly #italiansummer #italy,” the 51-year-old wrote in the caption.

For the cover photo, Frankel stood in the stern of a boat, wearing a white leotard with tiny stylish holes along the hips and chest regions, while her brown tresses flowed long and voluminous.

She gave her 2.7million Instagram fans and followers a better look at the classy number in a video that shows her aboard the boat in the distance, with the water and green hills in the background.

Frankel, who went on holiday with fiancé Paul Bernon around July 4, also slipped into a colorful chevron one-piece suit.

While wearing this particular swimsuit, which featured different colors along the bust lining, she decided to pull her long locks up into a bun to wear a hat and light-frame sunglasses.

In all, she posed for three photos in the suit, including two taken on a dock area near the water and another showing her lounging in a pool next to the waterway.

For this one, she kept her brunette locks in a bun but got rid of the hat.

She capped off her swimsuit modeling with a red bikini that also featured that stylish little opening along the bust region, similar to the white one-piece she wore.
