Sydney Sweeney took a page out of the 1910s Edwardian-era stylebook and gave it a modern spin to walk the red carpet at South by Southwest on Tuesday.

The Anyone but You star stepped out in a bridal custom Richard Quinn gown in off-white lace, with a silky off-the-shoulder neckline. The piece featured a cinched bodice and an ample poplin skirt with a high leg slit on one side. Peeking out were Sweeney’s white thigh-high lace stockings in a romantic floral design—a nod to both luxurious 1900s hosiery and to the current exposed-lingerie movement.
