Sydney Sweeney stepped onto the Emmys 2025 red carpet in a plunging, strapless red silk gown by Oscar de la Renta, finishing the look with an array of Lorraine Schwartz diamonds as she prepared to present at the televised ceremony.
The 28-year-old actress and producer wore a reported 120-carat diamond necklace, more than 30 carats of pear-shaped drop earrings and roughly 25 carats of diamond rings. She kept her styling classic with a sleek blowout and minimal additional accessories.
Sweeney, widely visible across fashion campaigns and film festivals this year, last attended the Emmys in 2022 when she earned nominations for her performances in Euphoria and the first season of The White Lotus. At that ceremony she wore a custom floral-appliquéd Oscar de la Renta gown and later changed into a cutout Versace dress at an HBO after-party; she also accessorized then with Lorraine Schwartz jewels.
Her presence at the Emmys follows a busy summer of projects and appearances. Sweeney launched a limited-edition menu with Baskin-Robbins, starred in a high-profile American Eagle denim campaign that drew controversy as well as commercial attention, and appeared in Jimmy Choo advertising wearing knee-high boots paired with a leotard. She also stars in the sports biopic Christy, which premiered earlier this month at the Toronto International Film Festival, where she showcased a range of festival looks from a custom Monse suit to a corseted pale-pink Erdem gown.
Offstage, Sweeney celebrated her 28th birthday this year and has been publicly linked to music executive Scooter Braun following a split with her former fiancé, Jonathan Davino, earlier in 2025. The pair were first seen together at a high-profile wedding in Venice in June.
Sweeney continues to expand her profile as both an actress and producer, maintaining a steady presence across fashion, film and marketing campaigns while participating in awards-season programming.
