Sienna Miller

Sienna Miller has had quite the summer. She admitted she's lazy when it comes to personal hygiene, she called a radio-host a douche-bag and she started dating a DJ with douche-bag name: Slinky Wizard is no Balthazar Getty.

But as much as people hate on the blonde Brit, you gotta admit she looked like a polished party princess at Vogue's The September Issue premiere. We'd never want to mimic her outlook on men or showering, but here's how to get Sienna's stylish look for less:   

Forever 21 Luster Party Dress


Forever 21's Luster Party Dress ($27.80) has the same bubble hem as Sienna's Thakoon mini. But the lightly padded bust helps out the girls while the adjustable straps make sure they don't have their own paparazzi moment.

KH Studio Designs Two-Tone Disc Chandelier Earrings


Chandelier earrings bring Sienna's signature bohemian vibe to any outfit. The two-tone metal discs on KH Studio Designs earrings ($40) mean you don't have to worry about mixing silver and gold accessories.




La Regale 25440 Clutch


La Regale 25440 pewter clutch ($45) is just big enough to store some lippy, a celly and an extra pair of knickers in case you accidentally wet yourself.




Michael Antonio Women's Shannon Platform


Michael Antonio Shannon sandals ($39.95 $30.91) have a platform heel, giving you long golden stems like Sienna. Who knows? Maybe they'll even help you bag your own DJ.
