Gymnast Olivia Dunne In String Bikini Warned About Her 'Good Genes'

Olivia Dunne stunned fans with her stars 'n stripes bikini last month, although the Instagram repost was a throwback. Showing off her stunning figure while in jeans and a cowboy hat, Olivia flaunted her gymnast figure in a photo used to promote Accelerator beverages — the original share, posted in July 2023, came as Olivia's debut with the energy drinks brand. Looking incredible in her halterneck swimsuit, the 23-year-old showed off her tan lines while enjoying a beach, and it looks like fans are nowhere near done reposting the photos. In September, the fan feed reminded everyone of Livvy's 2023 body, however the "good genes" comment was very 2025.

Scroll for all the photos. Showing off her sculpted shoulders and back in one photo, Olivia stunned in a barely there bikini in blue, white, and red.

Shouting out the U.S.A., the LSU graduate wowed with her slim waist while wearing blue jeans, also injecting Western accents from her straw cowboy hat.

Posing with her hair down as she gazed over sand dunes, Olivia nailed her all-American babe vibe, with another photo in her gallery showing her angling her hip as she posed by a wooden fence and with her jeans lowered. This time flashing her cleavage and rock-hard abs, the Vuori Clothing ambassador held a can of Accelerator, looking sunkissed as she smiled for her snap.

"Throwback to Livvy's summer full of Beaches and Tans," the fan repost said. Quickly commenting and referencing actress Sydney Sweeney's American Eagle "good genes" drama, one fan replied: "Watch out before your good genes are topic for racial debate.. be proud always." Olivia's OG post, which is still live, sits at over 500,000 likes.

Olivia Dunne now has three SI Swim features under her belt, although it was her May 2025 Cover Girl shoot that made the biggest headlines.

Sizzling in this black swimsuit for the magazine, the stunner flaunted her petite frame from the ocean, rocking a cut-out bathing suit with a strapless, bandeau finish. “I remember the first time I dreamt about Sports Illustrated and getting to work with SI. It was literally just a dream of mine,” Olivia toldSI Swim about landing her first cover. “ ... I feel like I manifested it into my reality today ... It’s been a blast, it changed my career. I would say to my 16-year-old self, just keep doing what you’re doing because you’ll end up here. This is crazy.”

Olivia Dunne sizzled in her tuxedo-style outfit for this year's MTV VMAs, showing off an ab-baring look as she rocked a tailored jacket and pants with a sexy satin bra.

For her glam night, she opted for all black, jokingly writing that the night "suited me well."
