Stylist Chiara Totire, before Sella McCartney, Paris, October 2013.
A beautiful white-on-white look for autumn/winter on gorgeous Chiara. And an innovative way to wear a crop top: underneath a sheer sweater (I think Chiara's crop top is from Zara).
Recreate Chiara's look (kind of):
Stella McCartney sweater, Vince sheer panel cashmere sweater,  Inhabit cashmere shaker sweater, Topshop cable jumper or Velvet cashmere classic turtleneck sweater
Wide leg pants: Philosophy satin wide leg pants, Joseph washed-silk wide leg pants, Alice + Olivia Eric pants, Vince silk strapping trousers, AQ Laurent wide leg pant, or J.Mendel wide leg pants
