Sienna Miller Just Wore the Pretty Colour Trend That Everyone Will Be Wearing in 2025

At this point in my career as a fashion journalist, I've learnt that there are only a few constants in the industry, and Sienna Miller being a Chloé girl through and through is definitely one of them. Having spent many hours studying the actor's wardrobe, I've found that it's easier to count the occasions that she isn't wearing Chloé than when she is.

Often showcasing yet-to-be-released pieces with Chloé's signature boho tell, and other times wearing cult buys that any editor would recognise in a moment, Miller's allegiance to the French brand has never been up for dispute. Taking her well-earned place on Chloé's front row at the brand's runway show in Paris, Miller wore a floaty, pleated jacket in a sky blue shade with a pair of dusty pink suede trousers.

Styling a fresh and airy colour palette, Miller nodded to the soft pastel shades that are set to dominate in 2025. A stark retort to the leopard print and vivid red trends that have been a key focus this year, next year's colours mimic the prettier shades we often see bloom in springtime, offering a lighter and brighter way of getting dressed when the weather follows suit. Seen across several runway shows over the past few weeks of fashion month, including at Ferragamo, Fendi and Jil Sander, the S/S 25 runways have spotlighted pastel colours as a big trend for next year. Naturally, Miller is already ahead of the curve.

Finishing her look with '70s-inspired accessories, Miller slipped into a pair of Chloé's peep-toe clogs and added a pair of oversized sunglasses, layering a few bangles on her wrists. With a penchant for all things lacy, floaty and boho-adjacent, it's no surprise to see Miller embrace such a pretty look.
