Amanda Seyfried Glitters in Monse

Amanda Seyfried glittered nearly from head to toe in her Monse strapless dress for the premiere of “The Housemaid” in Los Angeles on Monday night.

The Oscar-nominated “Mank” star, who collaborated with stylist Elizabeth Stewart on her look, wore a shimmering red dress from the New York City-based luxury apparel label’s pre-fall 2026 collection.

The dress was designed with a playful, modern approach to red carpet attire. Seyfried’s strapless Monse dress was crafted with glossy, structured fabric, featuring a fitted bodice with a cinched waist for added silhouette definition and a flowing skirt with a thigh-high slit.

Seyfried paired the dress with a statement necklace from Tiffany & Co. The Tiffany High Jewelry Pisces necklace featured an unenhanced orange sapphire of more than 23 carats. Taking more than 1,000 hours to craft, the platinum and 18-karat gold necklace also featured un-enhanced Umba and padparadscha sapphires, orange sapphires, rubellites and diamonds. The necklace was previously worn by Dua Lipa at the 2024 Grammy Awards.

As for footwear, Seyfried wore strappy Jimmy Choo heels. Her glam team, including hairstylist Jenny Cho and makeup artist Genevieve Herr, featured the actress’ blond hair with a middle part and makeup highlights including lined eyes, bold brows and a pink lip.

In contrast to her “The Testament of Ann Lee” promotional tour wardrobe, Seyfried’s “The Housemaid” premiere looks have gone the flirty route with a touch of modernity. Prior to the film’s Los Angeles premiere, Seyfried attended a screening for “The Housemaid” in New York City, wearing a pink liquid jersey Versace gown by creative director Dario Vitale.

“The Housemaid” follows Millie, played by Sydney Sweeney, who takes a job as a live-in maid for affluent couple Nina and Andrew, played by Seyfried and Brandon Sklenar, only to discover that the pair’s idyllic life isn’t at all what it seems. The film hits theaters Friday.
