Sienna Miller In Isabel Marant - W Magazine Celebrate The Golden Globes

Sienna Miller didn’t take to the red carpet at the Chateau Marmont for W Magazine’s celebration of the Golden Globes, but she was spotted inside.

Like many celebs, the British actress skipped wearing a Fall 2012 look for this Isabel Marant Spring 2013 dress.

Her ‘Natacha’ one-shoulder printed eyelet dress with a ruffled waist and wrap construction on the skirt was styled with red pointy pumps to complement the red embroidery on her dress.

For someone as petite as Sienna, this dress should be a perfect fit for her, but for some reason it makes her look a tad boxy as the dress appears to be too big for her.
