If the bevy of designers, like J.Mendel and Derek Lam, showing Winter white on their Fall '12 runways didn't convince you to embrace the trend, maybe Olivia Palermo will. The style setter transformed a pair of leather bottoms and a dark, cozy knit with her choice of outerwear — a chic cowl-neck coat in a cool Winter white. So just why does it work so well? Against her other, more basic seasonal wares, it's a fresh contrast that takes the focus and shapes the whole look into something more sophisticated. All she really needed to complete the ensemble was a perfectly polished pair of heels. Feeling inspired?
