Style file: Sienna Miller

Since bursting on to the showbiz scene back in 2003 on the arm of her then boyfriend Jude Law, Sienna Miller has well and truly undergone a style evolution.The blonde beauty has traded in her sun dresses and floppy hats for more streamlined silhouettes exuding grown-up and polished glamour from the likes of designers such as Dior and Burberry.

Fast forward over a decade, and Miller is still every inch the fashion maven she once was; she now incorporates her former trademark style into lady-like sophistication with the addition of floral motifs and daring cut-out panels, channelling her former hippie self. We take a look at her most memorable red carpet looks.

At the Valentino 45^th Anniversary Celebration in 2007, Sienna Miller stunned in a bright red floor length dress by the designer. Miller paired the feathered dress with a matching glossy red lip and a sleek chignon, making the look timeless and effortlessly sophisticated.

Miller turned heads at the LA premiere of GI Joe: The Rise of the Cobra, in which she starred as a raven-haired femme fatale. But at the premiere she embodied old-school Hollywood glamour as she wore a retro gold beaded Yves Saint Laurent dress. The look was kept timeless and elegant as she wore a deep red lip and curled locks swept to one side.

In October 2012, Miller made her first red carpet appearance since the birth of her daughter, Marlowe in July, and stunned in a classic white floor length Alessandra Rich gown.  She showed off her post-pregnancy body in the A-line dress, which featured caped sleeves whilst she accessorised with a gold bangle by Found Collected and a clutch by Charlotte Olympia.

At the BAFTA LA Awards Season Tea Party in 2013, Miller was the epitome of lady-like elegance in a pale pink Valentino Spring 2013 dress. The dress featured a delicately embroidered body and bracelet-length sleeves, making it the perfect choice for a tea party. Nude Christian Louboutin heels completed the look, whilst her pretty make-up and fuss free loose waves, kept the outfit girly and ethereal.

Sienna Miller showed off her tousled, cropped locks in a stunning Burberry dress at the 60^th London Evening Standard Theatre Awards in November 2014. Miller looked flawless in the pink and silver off-the-shoulder lace Burberry creation, whilst she channelled her inner boho goddess with her hair teased to perfection, simple make-up and minimal accessories.

At this year’s 72^nd Golden Globe Awards, Sienna Miller stunned in a dress by one of her favourite designers, Miu Miu. Miller opted for the beaded cream dress, which featured intricate embellishments and a deep, plunging neckline whilst she accessorised with gold Jimmy Choo heels. She wore dewy, bronzed make-up and opted for natural beachy waves, making this look one of the best on the night.
