Sydney Sweeney wears sheer lingerie to the theater in sizzling Syrn video

Sydney Sweeney’s back for round two.

The actress has been promoting her Syrn lingerie line practically nonstop over the past few months, and on Tuesday, she posted a smoldering theater-themed video to accompany her brand’s second Seductress drop.

In the vintage-style clip, 28-year-old Sweeney shows off the range’s white Fantasy Lace Halter Bodysuit ($89) — which features a high neck, an open back and a curve-framing cutout in front — along with matching thigh-high stockings, using opera glasses and an old-school popcorn box as props.

“Round two, she’s ready. Seductress Drop 2 now LIVE,” the post was captioned.

Syrn’s Instagram account has been teasing the capsule for the past few days, sharing campaign photos of its founder accessorizing her lacy lingerie with some strategically-placed roses.

The brand launched with an initial four “worlds.” First came Seductress, then Comfy; Romantic followed, concluding with Playful.

Each drop, of course, was accompanied by sultry campaign images of Sweeney, modeling everything from layered bralettes (for the Comfy launch) to marabou-trimmed robes (for the Romantic release) to fuchsia lace and faux fur (for Seductress).

With Syrn now rolling out second drops of its four core collections, fans can expect plenty more scandalously stylish shots to come.
