Sienna Miller shows off toned

Sienna Miller has always been known for her ability to make a fashion statement.

And once again the 31-year-old English actress did not disappoint with her wardrobe choice for both the 2013 British Fashion Awards and Playboy's 60th anniversary party, when she arrived in an emerald gown, with a leg-revealing split.

The star, with her newly dyed pink hair, was first spotted at the BFA's at the London Coliseum with her fiance Tom Sturridge, before moving on to the Playboy party on Monday evening.

Sienna's reveling outfit showed off her slender and incredibly toned legs to perfection, as she sauntered in and out of the different parties.

The Alfie actress teamed her silk Burberry gown with a white shearling jacket and a pair of Vintage strappy Burberry silver heels, a Roland Mouret gold clutch, chunky silver circular Dominic Jones necklace and drop earrings.

Her newly pink highlighted blonde tresses was left in her signature bohemian waves whilst keeping her make-up in a similar stripped back style, wearing just a touch of black eyeliner, mascara, cheek highlighter and nude lipstick.

Sienna, who is currently filming American comedy Business Trip and is set to star in Drama Mississippi Grind, attended both events, like many other celebrities including Rita Ora and Kate Moss on the evening.

Accompanying the star for the evening was her fiance Tom Sturridge, and both put on a very stylish display as they made a rare red carpet appearance together.

Adding to the fashion credentials, the pair cemented their standing in the sartorial world when they became the joint faces of Burberry earlier this year.

Heading off to the Playboy party, Sienna was escorted out of the London Coliseum by bouncers, before joining other well-known faces at the Playboy Club, London, such as Poppy Delevingne.

With cocktails in hand, the pair posed for the cameras, with Poppy dressed in a cute white mini dress, adorned with grand pianos and piano keys.

Featuring flattering ruffle detail, swathes of draped fabric and an elegant train, Sienna's choice of dress ensured she stood out from the rather stylish crowd.

And Tom certainly didn't let his leading lady down in the sartorial stakes, looking every inch the dapper dude in a slick two-piece suit, which he teamed with a crisp white shirt and a skinny tie.
