Sydney Sweeney is teasing another playful addition to her lingerie label, SYRN. The actress shared a photo and a short campaign video promoting the brand’s upcoming “Birthday Boobs” collection. In one of the clips, she went topless in only a cheeky low-rise g-string. The romantic-themed launch arrives on September 1, just days before Sweeney celebrates her 29th birthday.
Sydney Sweeney struts her stuff topless in only a cheeky low-rise SYRN g-string for birthday collection
For the ad campaign, before going topless in a cheeky g-string, Sydney Sweeney modeled SYRN’s Fall For Me Unlined Plunge Bra in the Blue Ditsy colorway. The sheer light blue bra featured delicate floral embroidery, soft underwire cups, and a tiny bow at the center. The close-up portrait highlighted the intricate lace detailing, while showcasing the collection’s feminine aesthetic.
The accompanying video offered a playful look at more pieces from the “Birthday Boobs” collection. In one of the clips, Sweeney appeared topless while covering her chest with two small pink-frosted cakes. She paired the cheeky styling with the Between The Lines Low Rise G-String in a matching floral print, creating one of the campaign’s most eye-catching moments.
Later in the clip, she changed into a coordinated black lace set featuring a floral bra, matching thong, Hold on Tight Garter Belt, and thigh-high stockings. She posed around a candlelit dining table decorated with cakes, roses, sparkling glasses, and ornate gold-framed mirrors, reinforcing the collection’s romantic, vintage-inspired mood.
Her glam remained soft and doll-like throughout the campaign. Sweeney wore her long golden-blonde hair in voluminous loose waves with a side part. Her makeup featured dramatic doll-inspired lashes, softly defined eyes, rosy pink blush, glowing skin, and matte soft pink lips, complementing the delicate lingerie.
The campaign also reflects SYRN’s growing identity. Founded by Sweeney in January 2026, the lingerie label offers 44 bra sizes across four signature collections: Seductress, Romantic, Playful, and Comfy. Most pieces are priced under $100, with the brand focusing on comfortable fits, feminine details, and confidence through everyday lingerie.
