Sydney Sweeney's lingerie brand, Syrn, recently shared a series of throwback photos on Instagram featuring the actress in various lingerie sets. The post, which included a slideshow of Sweeney in bras, panties, and crop tops, was accompanied by a caption that has ignited discussion among fans.

The caption read, "On Syd's Rack. From Syd's boobs to yours, shop her favorite looks on SYRN.com." This phrasing, along with images of Sweeney in revealing outfits, has drawn mixed reactions in the comments section.

Among the photos shared was a black-and-white image of Sweeney posing in a camisole and boyshort combination, similar to an outfit featured in a previous video. Another snapshot showed her leaning out of a window in a white lace bralette, matching underwear, and a sheer, fur-trimmed robe. Her hair was styled in voluminous curls, and she appeared to look coyly into the distance.

Additional images included Sweeney in a lace lingerie set with a garter belt and ribbons. She was also pictured in a sporty-inspired outfit at a gas station, wearing a red crop top over a bralette that displayed the words "Marry me, fly free." The top was paired with darker red shorts, and she was accompanied by two other models in similar attire.

The post promotes a collection of Sweeney's selected favorite lingerie pieces from her brand. A tagline on the Syrn website reads, "From the heart, brains and boobs of Sydney Sweeney." The featured items include garments such as the corset Sweeney wore while filming the HBO series Euphoria.

Sweeney has recently been vocal in defending her character Cassie Howard's storyline in the third and final season of Euphoria, which drew criticism from some viewers. She has also been working on a new film project in Australia and has been observed spending time with her boyfriend, Scooter Braun.
