Sydney Sweeney References Marilyn Monroe in a Curve-Skimming Gown

From the SCAD savanna film festival to The Academy Museum Gala, Sydney Sweeney has been appearing in sophisticated feminine looks. She wore a white dress to the premiere of “The Housemaid”on Monday, December 15, at the TCL Chinese Theatre in Los Angeles. The look referenced Marilyn Monroe’s plunging white gown she debuted during the 1955 film “The Seven-Year Itch”.

The custom white gown was designed by bridal brand Galia Lahav. Made from silk chiffon, the dress had a draped halter neckline with a tight fitted waist and feather detailing along the hem.

She styled her blonde hair in soft waves and paired the look with a bold red lip, nude eye makeup, diamond earrings, and a statement bracelet. Sweeney was joined on the carpet by Amanda Seyfried, who wore a shimmering red gown from Monse’s pre-fall 2026 collection.

“The Housemaid” is a psychological thriller adapted from Freida McFadden’s 2022 novel and directed by Paul Feig. Sweeney stars as Millie, a young woman whose new job begins to take a darker turn alongside Amanda Seyfried, who plays Nina. In an interview with People, Sweeney and Seyfried talked about the bond they formed while working on the film, sharing how they often supported and offered advice to each other.

Later that evening, Sweeney changed into a strapless white mini dress with floral appliqués for the after-party at TAO. She paired the look with white lace Gia 100 pumps from Black Suede Studio.

Sydney Sweeney has been seen channeling a Marilyn Monroe’s signature early-1950s blonde hairstyle. Back in October, she attended the Dodgers game during the 2025 World Series in L.A. with a new bob.
