Brielle Biermann posted an eye-catching swimsuit image for her 1.3M Instagram followers this week.
The 23-year-old Don't Be Tardy TV star was in a green bikini designed by her Bravo star mother Kim Zolciak for her Salty K Swim line which will debut in June.
This comes after her younger sister Ariana Biermann, who is only 18-years-old, did the same but chose a pink suit.

Earlier her teen sister shared two images to Instagram that were a reminder she is the daughter of the Real Housewives Of Atlanta star.
Not only did the teen look fit in her pink bikini - which was designed by Kim - but she also wore her hair long and highlighted, and had long nails.

The budding Instagram star - whose birth father is Kim's ex-husband Daniel Toce - said she was happy as she modeled a swimsuit made by her mother called Salty K.

Kim, whose bikini range will go on sale in just over two weeks, modeled a similar skimpy lilac swimsuit on Instagram last month.
Arinna - who has starred on RHOA, Don't Be Tardy and Don't Be Tardy For The wedding - has gradually been adopting her mother's look over the years.
When she opened her Instagram account in 2015 at the age of 13, she posted throwback images to when she was just a child.

But by 2016 Arianna was modeling a bikini as she chatted up a gift box and tagged the sponsor just like a pro.
And the next year, when she was 15-years-old, she adopted her mother's trademark long blonde hair thanks to a professional dye job at mom's salon.
In 2017 she was wearing a full face of makeup with false eyelashes like Kim and even added some blue streaks to her hair.
By the summer of 2017, bikini posts became the norm for the star who was keeping up with older sister Brielle, 23, as well.
And at the end of 2017 she was posing with her boyfriend Collin Lipman.
At 16, she seemed to mix with other celebrities as she was seen posing with Post Malone. The next year she took a photo with Future at a party.
Her mother Kim has become one of the biggest bombshells of the Bravo network.
And she has shared with fans over the years how she has maintained her great looks.
