Chinese model Fei Fei Sun, Tuileries, Paris, March 2013.
A beautiful white (high-maintenance!) coat with a hint of leopard and leather = winter in style. 
Recreate Fei Fei's look (kind of):
Roland Mouret Vallenar two-tone coat, Topshop Popper Front Boyfriend coat, Helmut Lang Apex Raglan sleeve coat, or Maiyet ribbed jaquard trench coat
Helmut Lang Stretch leather pants, Current/Elliott Ankle skinny leather pants, Topshop Boutique leather trousers, or Gucci stretch-leather pants
Leopard print booties: Miu Miu leopard print boots, Marais USA Ringo booties, Wood Wood Thelma leopard boots, or Christian Louboutin Tounoir ankle boots
