Sydney Sweeney has embraced a white-themed wardrobe during her appearances at the Venice Film Festival, featuring two distinct strapless dresses.

For a dinner engagement on Wednesday, Sweeney wore a vintage ivory strapless Chanel dress from the house's Spring 1987 collection, designed by Karl Lagerfeld. The gown, sourced from vintage dealer Raffe Vintage, featured a sweetheart neckline, a gathered bodice, and a sash detail. She paired this with a chocolate brown Chanel crescent bag, white mules, and sunglasses. The actress was accompanied by her hairstylist Glen Coco and makeup artist Melissa Hernandez.

The following day, Thursday, Sweeney was seen on a boat in a different white strapless design, this one a shorter, brighter mini dress. This daytime look was accessorized with a black clutch, a diamond bracelet, and dark sunglasses. Her hair was styled sleek and straight.

Sweeney is attending the 83rd Venice International Film Festival in her role as an ambassador for Armani Beauty, the official beauty sponsor of the event. Her festival fashion began on Wednesday with a sheer lace vintage Georges Chakra top, khaki Bermuda shorts, and clear PVC mules.

The city of Venice holds personal significance for Sweeney, as she and her boyfriend, Scooter Braun, first met there in June 2025 at the wedding of Jeff Bezos and Lauren Sánchez. The couple has since become more serious, with Sweeney recently spending time with Braun's children in Los Angeles, and Braun later joining her for a gondola ride in Venice.
