Sienna Miller Covers British Vogue, October 2015.

It takes a real fashion icon to appear on the cover of Vogue more than once, but Sienna Miller has done just that. After gracing the cover in December 2004, February 2006, September 2007, December 2007 and October 2009, October 2015 marks Ms. Miller's SIXTH cover, and it's a cracker. In this post, I'll take a look through some of her style highlights from recent years, and see why she's been picked to fill the cover slot on so many occasions.

The first look of Sienna's that I'm going to take a look at, is when she wore a custom Burberry gown to the Evening Standard Theatre Awards in 2014. After fronting the Autumn/Winter 2013 campaign with her then fiancé Tom Sturridge for Burberry, she has made several public appearances wearing the brand.

The next look comes all the way from 2012. Sienna wore an off-white caped dress by Alessandra Rich to the Chairman's Reception Dinner during the Hamptons International Film Festival. Her hair and makeup are absolute perfection here.

The third look that I absolutely loved was for the American Sniper premiere where Sienna wore Spring/Summer 2015 Balenciaga. Proving that she can work even the most unconventional trends, this look made sure she stood out in all the right reasons.

At this year's Golden Globes, Sienna was without a doubt, the best dressed attendee. Wearing a custom Miu Miu gown. The silhouette was modern, the embellishment made it dressy and her tousled bob looked incredible.

Back to Burberry for the next look. After appearing in the Autumn/Winter 2013 campaign, Sienna attended the Spring/Summer 2014 runway show dressed in Prorsum - the brand's most premium collection. I love the mix of textures - that fur cropped bomber is to die for.

Finally in 2014, Sienna attended pal Kate Moss' final collection launch for Topshop, wearing one of the designs. Sienna's tanned pins and ankle boots complimented the sparkly mini dress perfectly.

And now for the cover... well, there's two. Cue Brooklyn Beckham who's the star of this edition of Miss Vogue!

 If style files are right up your street, why not take a look at some of my others! Poppy Delevingne, Bella Thorne and Olivia Palermo are just some star's styles that I've explored.

In addition to a Vogue cover, Sienna also debuted a brand new look this week. Cue a fiery red bob, see above!
