Sydney Sweeney is a blond bombshell in Syrn lace lingerie

Sydney Sweeney is ready for her close-up.

The “Euphoria” alum, 28, stripped down to lace and fur for the latest campaign for Syrn, her lingerie brand, shared to the label’s Instagram on Tuesday.

Sweeney modeled the Forget Me Not balconette bra ($59) in the ivory “Cheerio” colorway, styling the bra under a sheer white robe with a plush collar.

“Syd for Romantic,” the brand captioned the three-part carousel — a nod to Syrn’s second collection, which the actress launched in February with a suburban-Americana shoot complete with rose bushes and a red riding lawnmower.

The post included a close-up mirror selfie of Sweeney snapping a camera in just the balconette and a behind-the-scenes clip of the sheer robe slipping off her shoulder.

Bombshell blond waves, smudged eyeliner and a lived-in dressing room set the Old Hollywood tone.

The “Anyone But You” star has been Syrn’s most frequent model since the Jeff Bezos-backed label’s January launch, recently stripping down to strappy black lace from the Seductress line and a plunging sheer bodysuit earlier in July.

Most recently, she showed off her behind in an all-black lingerie set that included a lacy bra, similar fur stole and strappy thong.
