Sydney Sweeney revealed a striking new brunette updo to promote her thriller-survival movie Eden, marking a sharp departure from her familiar golden-blonde hairstyle. This chestnut-colored style highlights the actress’s evolving hair transformations and fresh portrayal for the film’s 1930s setting.
Known for her versatility with hair colors and styles, Sweeney has dazzled fans by shifting from her signature long blonde locks to diverse looks, including an inky-black bob with bangs at the 2024 Met Gala, punk-inspired updos, and strawberry-blonde curls. Her natural brunette roots shine through this latest deep brown updo, enhancing the period aesthetic of her new role.
Fashion and Hair: A Vintage-Inspired Ensemble
The 27-year-old actress shared a series of Instagram snapshots from the Eden set, where her glossy chestnut hair is swept into a neat, voluminous updo reminiscent of styles from past eras. This hairstyle complements multiple 1930s-inspired outfits, reinforcing the film’s time period and tone.
One ensemble features a baby-blue polka dot co-ord with a button-up short-sleeve top and a flowing midi skirt, paired with classic white sneakers for a casual yet elegant look. Alternately, Sweeney swaps the sneakers for brown leather Mary Jane flats with double straps, adding a vintage charm that enhances the overall styling.

Other costumes include a cinched white patterned blouse worn with a gray midi skirt and the same sneakers, as well as a white polka-dot dress with cap sleeves and a crossover neckline, all evoking an authentic period feel.
Additional Styling Reflects Character and Era
Further outfit changes show Sweeney dressed in a white patterned dress beneath a white button-down shirt, accessorized with a floppy sunhat and a mauve-pink scarf, adding softness and texture to her on-screen persona. Another dress features a dark-green floral print layered over a lighter-green floral T-shirt, creating a layered look true to the 1930s fashion influences throughout the film.
Contrasting Looks with Costars Highlight Dramatic Hair Shift
To emphasize the extent of her hair transformation, Sweeney posted a photo alongside fellow stars Ana de Armas and Daniel Brühl where she appears with her everyday hair—light blonde waves parted in the middle—off set. In this casual moment, she wore an oversized black Alo hoodie and matching leggings, presenting a stark contrast to her character’s sophisticated on-screen image.
