Sydney Sweeney bares her sculpted physique as she pairs a swimsuit with lace thigh highs for new images from her collection with Frankies Bikinis

Sydney Sweeney was a classic bombshell in a sizzling new Instagram album for her swimwear collection with Frankies Bikinis.

The 25-year-old Euphoria star showed off her chiseled beach body as she lounged around on a sofa for a string of jaw-dropping shots.

She was modeling the collection’s ‘key lime’ two-piece, which was embroidered with a subtle pink floral pattern around the edges.

Sharpening her winning features with makeup, she lent the look a splash of dazzle with a thick choker, swinging hoop earrings and an ornate cross.

Jazzing up the look even further, she set pulses racing in a set of white lace stockings and a pair of ankle-strap flats.

Frankies Bikinis was founded a decade ago by Francesca Aiello, 27, who designed swimsuits with her mother Mimi for a brand that has become an influencer magnet.

Now Sydney, who has become one of America’s top pinups, has lent her talents to a new Frankies Bikinis collection influenced by summertime in Italy.

She told Elle that Francesca caught sight of her wearing Frankies Bikinis on Euphoria, which ‘sparked the conversation’ that led to their team-up.

‘We met in person at her Venice office and instantly hit it off. We were throwing around ideas and mood boards,’ said the White Lotus actress.

Letting the fans in on the thought process behind the swimsuits, she dished: ‘We felt Rome really captured and invoked the feelings behind the collection.’

She added: ‘We wanted a space that complimented the details on the pieces, but also somewhere we had the freedom to move and play.’

Sydney dished: ‘I was actually filming Immaculate in Rome during that time, so I was there for four months! I love Italy. I’m in Australia now filming, and wearing my pieces almost everyday. It’s the perfect place: beach, hot, sunny, and romantic!’

Her decision to break into the bikini business stemmed from the fact she ‘grew up on the water, always running around in a bikini.’

Sydney, who was brought up in a lakefront home in the Idaho Panhandle, said: ‘If I wasn’t swimming in the lake or the ocean, I was skiing or attempting to surf.’

As a result, she explained, ‘there was always a part of me that wanted to create something that truly felt like me, and with Francesca and her incredible company, we really created something special.’

Her new collection with Frankies Bikinis includes a set of swimsuits with a lipstick mark design – based on Sydney’s own lips.

‘I was coating on different shades of red lipstick and kissing paper and sending pics to Francesca,’ Sydney dished, saying the undertaking was ‘both’ funny and sexy.

Francesca and Sydney had a ‘back and forth about how much my lips should be parted or [how much] color [I should apply], so my bathroom became covered with pages of my lipstick marks,’ the actress added.
