Sienna Miller Gives The Prairie Trend A New Meaning In A Michael Kors Collection Gown

Sienna Miller is like that one girl whose closet just never ends — a Bohemian treasure trove that seems to never have repeats, yet still manages to maintain a cohesive aesthetic of polished hippie. This is just what she gave us at the London premiere of High-Rise: Sienna Miller in a prairie dress basically confirmed that she's the queen of everything Bohème.

Check any best dressed list for music festivals, and you'll find Miller among the fashionable bunch. Whether she's rocking a draped floral frock with motorcycle boots, a belted patterned vest at Coachella, or a deep red suede cape over a green sweater at the Glastonbury Festival, she always looks perfectly messy, in the too-cool-for-school way I'm always trying to accomplish.

There's no one that can quite pull off the prairie trend like Miller can. So often, we see her pairing a white prairie-style dress with lace up boots — every Bohemian lover's uniform. Can we also talk about her use of hardware in her style? From bejeweled vests to studded belts, Miller isn't afraid to get her metal on. And don't even get me started on how good she looks in hats. It's almost infuriating!

So it comes as no surprise that at the movie's premiere, she looked stunning in Michael Kors Collection prairie gown, with a bit of a bell-sleeve and a floor-grazing skirt. While I usually just end up looking frumpy in a prairie-inspired ensemble, Miller looks fresh, young, and absolutely chic. She paired the dress with a small, rectangular clutch, simple bracelet, and her signature wavy locks.
