As she twirled for the camera, her wavy tresses billowed with her motion as she flaunted her cleavage and flat abs.
The website for Frankies Bikinis describes the collaboration with the Euphoria star as the sexiest yet.
‘Love Letters by Sydney Sweeney is inspired by the girl who follows her heart, with pieces that highlight Sydney’s gorgeous femininity and sweet romantic aura,’ the web page reads.
The actress turned designer has collaborated on a number of looks in a variety of colors, including green, pink and white.
‘This collection introduces bombshell bikini tops made to tease, one pieces made to flatter, clothing designed to inspire confidence, and personal details from Sydney herself.’
Earlier this week, the Once Upon a Time in Hollywood actress, who is in Sydney, Australia shooting her new film, took a break from filming to check out an Australian Rules Football match between the Sydney Swans and the Hawthorn Hawks.
In a video shared by the Sydney Swans, the actress couldn’t wipe the smile off her face as she chatted to the shirtless men and posed for photos with them.
‘When Sydney met the Swans. Thanks to the amazing Sydney Sweeney for visiting us,’ the clip was captioned.
The blonde put on a flirty display as she flashed her abs in a beige crop top and wore a Swans scarf for the locker room visit.
At the end of the video, she could be seen doing a cartwheel and giggling on the field.
Sydney attended the game at the Sydney Cricket Ground with her actor pals Dermot Mulroney and Rachel Griffiths.
They were there to cheer on the Swans as they took on Hawthorn, defeating them by 81 points.
