Sydney Sweeney Leaves Little To The Imagination In ‘Illegal’ Lingerie Snap

Sydney Sweeney is once again dominating timelines, and this time, it’s thanks to a fan account bringing back one of her most jaw-dropping looks. An Instagram page recently shared a sizzling photo of the "Euphoria" star, tagging her directly and captioning the post, “Model: @sydney_sweeney.” That was all it took to send the comment section into overdrive.

In the snap, Sweeney lounges across a gold vintage sofa, striking a pose with her arms stretched above her head. She wears a pastel green bikini paired with white lace thigh-high stockings and lavender heels, that immeditaely turned heads.

Fans wasted no time reacting. “Lordy,” one follower commented. Fire emojis quickly filled the thread, while another user bluntly wrote, “That’s f-cking illegal,” clearly stunned by the look.

While fan accounts continue resurfacing some of her most talked-about glam moments, Sweeney has also been making moves on the business front. The actress recently turned up the heat in a different way, by launching new campaign ads for her own lingerie brand, SYRN.

On February 2, 2026, the 28-year-old dropped a teaser titled “Somewhere Only We Know” on Instagram, giving fans their first glimpse at the dreamy new collection. The romantic clip featured Sweeney modeling several delicate lingerie sets in a soft, cinematic setting that instantly turned heads.

Just ten days later, on February 12, Sweeney and SYRN followed up with a second video to introduce the brand’s first “playful” collection. This time, the vibe was completely different.

The ad showed Sweeney alongside two other women creating cheeky chaos inside a corner store, laughing, running around, and fully embracing the fun energy of the campaign while wearing the new lingerie pieces.

Sweeney has been clear that SYRN is about more than just aesthetics. In a recent interview, she opened up about the deeper vision behind the brand and what she hopes it represents for women.

“I wanted to create a world and a feeling,” Sweeney told ELLE. “I wanted to build a lingerie brand that feels like it understands women instead of talking at them. Syrn is about confidence without pressure, feeling sexy, powerful, soft, playful, or all of the above, depending on the day."

The brand’s debut drop features lace-detailed underwear and easy, everyday bras available in an impressive 44 sizes, ranging from 30B to 42DDD. "As the sole founder, my vision was to create something that lives in real life and doesn’t hold anyone back," the actress added.

But for Sweeney, the mission didn’t stop at inclusive sizing. She’s also focused on the practical frustrations women deal with every day, from straps that dig into shoulders to bras that simply don’t fit the way they should. Instead of prioritizing style over substance, Sweeney says she was determined to create pieces that feel as good as they look.

“Boobs and bodies are like fingerprints; everyone’s are different, and I wanted to design for that,” she explained, emphasizing that comfort was just as important as confidence when building the line.

SYRN officially dropped on January 28.
