Sydney Sweeney turned heads at the Echo Valley premiere in London on June 10, 2025, showcasing her stunning style in a custom Tiffany blue Miu Miu dress.

The standout detail of her ensemble was a daring cutout over her chest, offering a glimpse of her figure and captivating onlookers.
To elevate her look, Sweeney adorned herself with exquisite diamond jewelry, including sparkling rings and stacked tennis bracelets on her left wrist. Her dangling diamond earrings by Davis Morris added the perfect touch of glamour. The actress completed her radiant appearance with soft bronzy eyeshadow, a hint of black eyeliner, long, flirty lashes, and a touch of pink on her lips.

In a recent interview with W Magazine, Sweeney candidly discussed her body transformation for her role as Christy Martin in an upcoming biopic. She revealed that she gained over 30 pounds in preparation for the part, stating, “My boobs got bigger. And my butt got huge. It was crazy! I was like, ‘Oh, my God.’” The actress explained that the weight gain required a complete wardrobe overhaul, as she had to adjust from her usual size 23 jeans to a size 27.
The 27-year-old star shared that her transformation was achieved through a rigorous training regimen over just three and a half months. “I started eating. I weight-trained in the morning for an hour, kickboxed midday for about two hours, and then weight-trained again at night for an hour,” she elaborated. Sweeney expressed her enthusiasm for the process, stating, “I loved it.”
