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 a Chloé item than when she is. Often sporting yet-to-be-released garments 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 at no point 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 of choice 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 a number of runway shows over the past few weeks of Fashion Month, including at Ferragamo, Fendi and Jil Sander, the spring/summer 2025 runways have enforced that pastel colours are going to be a big trend in a few months time. Naturally, Miller is already ahead of the curve.
