Sydney Sweeney has completed her lingerie brand launch.

With her last of four collections finally dropping Wednesday, March 4, the Comfy capsule is by far the most simple of her Syrn offerings.

In promotional photos shared by the brand, Sweeney wears a duo of high-waisted thongs and soft cotton bralettes, one set in white and another in black, layered on top of each other.

“Made for staying in, slow mornings or feeling your comfiest on the go,” reads the caption, adding the tagline, “Do What Makes You Naked.”

Syrn also released a video, featuring a behind-the-scenes look at Sweeney’s campaign.

In the clips, she poses in a myriad of tanks, briefs, bra tops and more — all in a variety of nude tones.

A third post simply depicts a pair of boyshorts being pulled over a model’s knees, bearing the brand’s logo on the waistline.

Last month, Sweeney launched Syrn with the brand’s Seductress collection, featuring more traditional lingerie styles including corsets, garters and bold imagery.

Next came Romantic, which was just as sultry, albeit a tad more feminine and included lots of lace.

Last week, she transitioned from lace to cotton with the introduction of Playful, featuring a retro sporty take on mix-and-match essentials.
