If you think you've seen this outfit before, it's because you probably have... it's a classic Kate Moss look. Nobody rocks leather and leopard like Ms Moss.
Bag: Vintage Chanel (more vintage Chanel here & here).
Shoes: Zara.
There's always the danger of looking like a bumble bee when wearing yellow and black. I fight it by adding a pop of another colour and breaking the black up with a print.
