Not afraid to flash the flesh, the 22-year-old stripped off to a very revealing ensemble as she partied in Brazil.
Donning a show-stopping jewelled bra, which featured a jaw-dropping cut-out design, the award-winning actress was barely able to contain her ample assets.
Flaunting her cleavage, the star narrowly avoided exposing her nipples in the sparkling ensemble.
Showing off her slender mid-riff, she teamed the statement piece with cream high-waisted hot pants, which had been embellished with beads.
The model completed the ensemble with sparkling fishnet tights and white trainers.
Soaking up the sun, Bruna had swept her sleek brunette tresses into a low pony tail.
Sporting a pair of silver square shades for the photoshoot, the stunner rocked the carnival chic look.
Opting for a fresh-faced look, the star opted for bold pink lipstick, and had adorned her body with glitter.
In one capture, the Brazilian beauty was pictured smouldering candidly as she gazed into the distance.
And, in another snap, Bruna revealed her svelte physique as she immersed herself in the festivities.
Beside the eye-popping upload, the supermodel wrote: “CARNAVAL”.
Fans were clearly impressed with the shots, with one writing what translated as: “Bruna, you have your style, you have attitude, you are beautiful, independent.”(sic)
Meanwhile, another admirer commented: “No comments for this beautiful girl .. just perfect.”(sic)
The photo came just hours after she treated her 26.1 million Instagram followers to a group photo from the day.
Pictured smouldering in the same outfit, she posted a caption which translated as: “Only in Bloco da Favorita do we find the extra layer of joy to enjoy the carnival!!!!”
