Sienna Miller Wore Two Major Summer 2024 Trends in Just 12 Hours on the Cannes Red Carpet

Sienna Miller may possess a very strong sense of personal style, but that doesn't mean that she isn't partial to experimenting with a new-season trend on occasion. Stepping out on the Cannes Film Festival 2024 red carpet, the actor chose the event to showcase her take on two growing summer trends.
Appearing at the Horizon: An American Saga premiere last night, Miller brought a fresh and spirited energy to the event by choosing a pale blue gown from French fashion house Chloé, of which we know she's a big fan. Selecting a pair of silver high heels for her sheer, ruffled dress, Miller accessorized her look with a simple silver necklace and her signature tousled waves. Letting the beautiful pale blue shade do the work, she kept the rest of her outfit simple for a relaxed take on red carpet dressing that felt perfectly in line with her style.
Earlier that day, Miller was spotted in yet another blossoming trend. Stepping out in an ensemble from couture fashion house Schiaparelli, she chose to style a pair of dark-wash barrel-leg jeans for a more low-key red carpet photo-call event. Wearing Schiaparelli's extra-wide, low-rise cowboy-inspired pants in indigo, the actor grounded the statement jeans by layering a classic boucle jacket up top, resulting in an unexpected yet elevated take on event dressing.
Although I love Miller's off-duty style, her event outfits never disappoint. To shop the new-season trends that she's already weaving into her wardrobe, read on to discover the best pale blue dresses and barrel-leg jeans.
