Sienna Miller Just Wore the Boho Dress and Boots Formula Everyone Will Copy This Autumn

When it comes to fashion, Sienna Miller is typically a season or two ahead of the rest of us. Somehow able to see into the future, the style icon seems to predict the upcoming season's biggest trends well before we've wrapped our heads around this season's.

Attending the L.A. premiere of her latest film Horizon: An American Saga, Miller stepped out in an elegant ensemble that looked fresh off an autumn mood board. Wearing a flowy white dress with lace embroidery, ruffle detailing and slim spaghetti straps from Chloé’s S/S 25 collection, the actor picked up on the key summer trend destined to seep into the latter half of the year, too.

Whilst we always see white midis and minidresses dominate throughout the warmer months, this autumn, we anticipate that hemlines will drop as the pretty white dress takes on a longline form. Treating us to the ultimate autumn-ready paring early, Miller wore her breezy dress with a pair of black knee-high boots, crafting a cool-weather look that remains loyal to her iconic boho-chic style. She took a pared-back approach to accessorising the look, selecting simple pieces that elevated her look effortlessly. Wearing an elegant gold choker and a dainty charm bracelet, Miller's jewellery added polish to the overall edgier look.
