Fashion darling Sienna Miller captured hearts back in the mid-2000s with her boho-infused It-girl aesthetic. Denim waistcoats, cowboy boots, studded belts and swathes of suede, the noughties style icon was ahead of her time – especially now that boho is back with a bang thanks to Chemena Kamali's debut show for hippy-adjacent designer label Chloé.
But Sienna's style prowess goes way beyond her golden era, as evidenced by some of her more recent fashion triumphs.
Picking only a few favourites demonstrated mighty restraint on our behalf, but do scroll on for some of the best outfit inspiration out there...
Cool Corduroy
Oh how we gasped when we saw this Chloé ensemble, worn to the SS25 show in Paris. The colour palette of dove grey and the palest blush pink is frankly the prettiest we've seen in a long time.
A masterclass in off-duty style that still packs a sartorial punch. Wide leg jeans paired with a slouchy blazer, cowboy boots and a gorgeous suede bag for a London stroll.
Balloon Jeans
At the Cannes photocall for Horizon: An American Saga, Sienna tapped into one of the hottest denim trends of the moment: balloon jeans. Expanding at the knee before tapering in at the ankle, the style is unexpectedly super flattering. Sienna paired her dark denim wash pair with a cream blazer with playful, surrealist gold motifs, courtesy of Schiaparelli.
Hippyish Skirt
The actress made her presence known at Paris Fashion Week in head-to-toe Chloé. She layered a whimsical white lace slip under a heavy-duty leather jacket and completed her ensemble with vertiginous wooden wedges.
Cool-Girl Skort
The Anatomy of a Scandal star went for simplicity, opting for a light collared knit, tinted shades and a black skort with a distinctly sporty feel.
Neutral Power Suit
Sharp and elegant, Sienna wore a beige double-breasted suit to Wimbledon with acetate accessories and kitten-heel mules.
70s Glam
The Burnt actress oozed sultry, 1970s spirit in a plunging camel and brown dress, styled alongside a mirrored clutch and blue suede platforms.
The Fresh White Midi
Sienna served up pretty, summer elegance in a lace Bardot dress, styled with a black leather belt focal point for a bit of edge. Her snakeskin T-bar sandals provided a sense of texture, and she opted for a blurred red lip for a pop of colour.
Sultry Lace Leggings
Sienna exuded after-hours sultriness in an all-black ensemble. The actress styled a cut-out LBD over stirrup-style lace leggings alongside a formal overcoat and stilettos.
Pinstripe Co-ord
The picture of easy-breezy summer cool, Sienna wore a blue and white striped shirt with matching wide-leg trousers and a cream top-handle bag.
Ruffle Knit
The actress was a 1970s dream in a ruffle multi-coloured knit and high-wasted jeans paired with a monochrome structured shoulder bag.
Groundbreaking Florals
The street style maven delivered a corker with this orange short-sleeved midaxi featuring a pretty daisy print. Sienna styled the piece with barely-there sandals and a gold clutch.
