The actress has long been compared to the legendary screen sirens of the past — and she clearly enjoys leaning into that timeless image.
On December 15, Sydney Sweeney and Amanda Seyfried unveiled their new high-stakes thriller The Housemaid in Los Angeles. For the red-carpet premiere at the TLC Chinese Theatre, 28-year-old Sweeney arrived in full old-Hollywood glamour, looking like she’d stepped straight out of a classic film era.

The Euphoria star stunned in a custom-made white gown by Galia Lahav, fwith a bold neckline and a feather-accented skirt. The look was pure vintage fantasy — the kind of outfit that could easily be imagined on Grace Kelly or Marilyn Monroe.

Sweeney completed the striking ensemble with dazzling Jacob & Co. jewelry, bold red lipstick, and sharp black eyeliner, creating a high-contrast, sultry finish. The Housemaid hits theaters on December 19, with a Russian release scheduled for January 8, 2026.
