What we love most about Sienna Miller’s style is how unpredictable it is; you never know what she might choose to wear next. Unconcerned with maintaining a specific aesthetic, the way Miller dresses is intrinsic to how she feels and what she’s drawn to. One day, we can just as easily spot her wearing ripped jeans, Birkenstock Bostons, and a puffer jacket on the school run, only for her to turn out looking polished in tailored trousers, a cashmere knit, and heels for the same endeavour the very next day. Truly, it’s fascinating to watch.
Seeing as she’s had a slew of major projects come to fruition this year, we’ve been treated to more Sienna sights—and, in turn, Sienna outfits—than we have in a long while. And her latest ensemble continues to hold her sartorial bar high. Last night, Sienna Miller attended the premiere of the film The Sandman, held at BFI Southbankin London. Although she doesn’t star in it herself, she was there to support her ex Tom Sturridge for his role in the film, and, naturally, she did so in style.
For the occasion, Sienna chose a knitted midi dress with an on-trend sweetheart neckline and bell sleeves from Self-Portrait, the brand editors and influencers wear regularly. Of course, the knitted dress trend always comes into its own in autumn when we look to trade in our lightweight linens and other fabrications for something a little heavier. But, true to form, Sienna remains one step ahead of the curve in her blue midi. Pairing it with white sandals and a bag to match, I could also see this dress working with minimal slider sandals, should you want to give it a relaxed spin.
As part of the brand’s new collection, you’ll be pleased to hear that Sienna Miller’s Self-Portrait knit dress remains in stock. Scroll down to see it and the black iteration too. Then continue on to shop our edit of other knitted dresses you can start wearing now and keep wearing well into winter.
