The look is quite a turnaround for the skinny British supermodel. Just weeks before, she sported shoulder-length locks to the opening of Topshop's Knightsbridge store, reports the Daily Mail; now, however, her hay-colored hair hung down well past her chest and olive Fiona Paxton Surat necklace.
Either someone's been tippling the Miracle-Gro, or we'd guess that Moss has had the help of more than a few hair extensions.
As for the 36-year-old's dark roots, don't think for a minute that this trendsetter couldn't be bothered to touch-up her tendrils. Visible roots are very much in style -- not unlike the gray streaks Moss showed off five months ago at her Longchamp handbag launch in Paris.
In fact, in recent months, stars including Mary-Kate and Ashley Olsen, Gwen Stefani, Sarah Jessica Parker, and a whole flock of winged Victoria's Secret Angels have kept their roots dye-free.
So there you have it: The answers behind Moss's new 'do.
Actually, we have one more question: The woman is worth millions - can't she afford a hairbrush?
