For the campaign, Sydney Sweeney modeled SYRN’s Balcony Scene Unlined Balconette, The Little Nothing Tanga, and Hold on Tight Garter Belt in the black colorway. The sheer floral lace balconette bra featured delicate bows on the straps and a subtle center cutout. Additionally, she paired the balconette bra with a matching cheeky thong and ruffled garter belt. As a result, the coordinated lingerie look drew direct inspiration from vintage romance.

One standout image captured Sweeney lying across an elegantly dressed dining table while eating slices of birthday cake. Frosting covered her fingers and spilled onto her chest, adding a playful twist to the glamorous setting. Meanwhile, soft candlelight, pink roses, sparkling wine, and an ornate gold mirror completed the dreamy, old-Hollywood atmosphere.

The second close-up highlighted the intricate lace details and the heart-shaped cake. It was decorated with the handwritten message, “I really really love you.” The phrase carries special meaning throughout the collection. Sydney revealed that her own handwritten words are embroidered into several pieces, describing the detail as “a love note you get to wear.”

Her beauty looked perfectly complemented the romantic campaign. Sweeney wore her long golden-blonde hair in soft, bouncy curls with a center part. Her makeup featured fluttery lashes, softly defined eyes, and rosy cheeks. Glowing skin and a soft pink lip further enhanced the collection’s feminine mood.

The “Birthday Boobs” collection falls under SYRN’s Romantic category and includes bras, thongs, camisoles, matching sets, and garter belts. Available in baby blue, baby pink, and black, the collection ranges from $19 to $64. Furthermore, the line spans sizes XXS through 3X across 44 distinct bra sizes.
