Sydney Sweeney is mopping the house floor with her nostalgic transformation.
The 28-year-old actress, who has been sporting a short bob for months, showed off glamorous Old Hollywood curls at the New York premiere of her new movie, The Housemaid, on December 2nd.
Sydney turned heads on the red carpet with her voluminous, curly hair. She kept her classic blonde color but styled it in bouncy 1970s-inspired curls that fell just below her shoulders. The Euphoria star completed her retro look with a shimmering silver Miu Miu gown, a fluffy white feather boa, and sparkling diamond earrings.
I was absolutely captivated by Amanda Seyfried’s look! She wore this stunning, flowing pink Versace gown with a really flattering neckline, and it looked incredible with her wavy hair styled to the side. She finished the whole thing off with beautiful silver jewelry – seriously, she was glowing!
Sydney has recently changed her hairstyle quite a bit from her previous bob. She last made a splash with a shorter cut, which she first showed off before playing boxer Christy Martin in the upcoming movie Christy. She debuted the look at Variety‘s Power of Women event in October, styling it with a flipped end and a sheer dress by Christian Cowan x Elias Matso.
Staying true to the event’s focus, the star of Anyone But You explained how playing a boxer helped her grow as an actress.
Sydney shared that she understood what it was like to be doubted and judged before people truly knew her. She also knew the feeling of having to constantly prove her worth and demonstrate that she belonged.
Sydney worked hard to get the part, making significant changes to her lifestyle, like switching to a diet rich in carbohydrates and starting a new exercise plan.
She told W magazine that when she began preparing for the role of Christy, she underwent an intense three-and-a-half-month training regimen. This included a strict diet and a rigorous workout schedule: an hour of weight training in the morning, two hours of kickboxing at midday, and another hour of weight training in the evening.
By the end of her 30-pound transformation, Sydney admitted she “didn’t fit in any of my clothes.”
“But it was amazing,” she clarified. “I was so strong, like crazy strong.”
