Nobody could say it was a run of the mill red carpet look.
Kate Bosworth turned heads at Sundance on Wednesday night in an arresting mid-century ensemble that worked with decidedly retro textures.
The 30-year-old looked stunning in a 'calfskin' simulated high necked sleeveless blouse cinched around her waist with a white belt that tied into her collar halter.

'60s chic: Kate Bosworth went for an arresting mid-century inspired outfit at the premiere of Big Sur at Sundance on Wednesday night; she met her director fiance on the movie
She finished off the look with some very era appropriate white PVC boots and slicked back her blonde hair Twiggy style.
Full marks have to be issued for era-appropriateness, and for taking a risk; but glacial Kate looked a little like a Bond assassin or fembot about to strike in the interesting combination.
Dressing for the 21st century was Kate's fiance Michael Polish, who looked dapper in a navy shirt and black suit.
The occasion was the Sundance premiere of Big Sur.

The pair met while filming the movie, which is based on the autobiographical novel of the same name by Beat Generation poet and novelist Jack Kerouac, and have been inseparable ever since.
The lovebirds finished working on the film which 41-year old Michael directs and Kate stars, at the beginning of this year but has not let that keep them apart.
They stepped out in public together a little over a year ago as they took in a Coldplay concert, shortly after Kate and her ex-boyfriend, True Blood actor Alexander Skarsgard, parted ways.
