Take a seat — Sydney Sweeney's latest campaign just dropped.

The “Euphoria†actress, 28, perched on a chair wearing nothing but a black thong and sheer tights in a new photo shoot for her lingerie brand, Syrn, dangling a handful of bras and tanks overhead for good measure.

The underwear is part of the brand's latest collection with the slogan “Do What Makes You Naked,†which launches Mar. 4 and is the first offerings from Syrn's “Comfy†line. It swaps the corsets and garter belts of earlier Syrn drops for scoop-neck bras and boy shorts made from what the brand calls “Seamless Stretch†fabric.

The chair moment was just one of several acrobatic poses Sweeney pulled off on set, as seen in a video posted to Syrn's Instagram. She also twisted into an “upside down chair pose,†a “lick the knee pose†and a “triangle hip lift pose†— all in the brand's barely-there basics.

The actress served as her own model for the campaign — a move she's made for every Syrn drop since the brand's January launch.

In a separate clip, the actress gave fans a behind-the-scenes tour of the lineup, pulling stretchy bralettes and underwear off a rack. “You can layer 'em. I like to mix 'em all up,†she said, wearing two layers of bras and boy shorts in contrasting colors.

Sweeney has modeled every Syrn campaign herself, following a playbook set by the early days of Rihanna's Savage x Fenty and Kim Kardashian's Skims. syrn/Instagram

The collection is designed for “all your coziest moments,†according to the brand, and features pieces made to “move without thinking about it.â€

Backed by Coatue Management — a venture capital fund with support from Jeff Bezos and Michael Dell — Syrn launched in January with its Seductress collection and a headline-grabbing stunt that saw Sweeney and her team drape bras across the Hollywood Sign.

The debut has since been followed by three additional “worlds†— “Romantic,†“Playful†and now “Comfy.â€
