BRIELLE Biermann, 23, flaunted her fit figure in a blue thong bikini from her mom Kim Zolciak’s swimsuit line.
While showing off the Salty K swimwear, Brielle also let her new brunette locks blow in the ocean breeze.
Brielle gave followers a view of her backside in the blue string, thong bikini.
She posed looking over her shoulder in the ocean.
In other shots, she was seen kneeling on the sand.
She wrote in her stories: “We’ll do anything for the best shot!”
Brielle has been helping to promote her mom and RHOA alum’s new swimsuit company, Salty K.
Last month, the new brunette showed off her tanned backside in another thong bikini writing on Instagram: “NEW @saltykswim swimsuit available tomorrow.”
Brielle wore her long brunette hair down under a pink bucket hat.
The accessory matched her sunglasses and cheeky baby pink bikini.
She also recently posed in a white bikini pic captioned: “SWIPE! Feeling confident and back to myself again after using my go-to self-tanner @lovingtanofficial!
“Loving tan is long lasting, easy to apply & gives you a natural glow Use my code: BRIELLEMITT for a free mitt with any mousse, gradual tan, shimmer or face tan purchase.
Kim responded: “Looking good baby! @saltykswim @lovingtanofficial look great together!”
Brielle’s 18-year-old sister, Ariana, has also been modeling her mom’s new swimwear designs.
The teen playfully posed in a new pink bikini, flipping her long brunette hair and looking over her shoulder.
On her Instagram stories, Kim, asked: “Ok you guys, what do you think of this suit, I just did it in a sample size for Ariana in the pink and I’m literally obsessed with it.
“Yes or no, help.”
The gorgeous pink bikini featured a ruffled v-shaped bottom and a spaghetti-strap balconette top.
