Scarf: Hermès
Shirt: Mango (similar)
Jeans: Topshop
Boots: Zara (similar)

Firstly, I'd like to apologise for my chronic bitch face in these's a serious problem and one I seemingly can't control. 

There's something about a silk scarf that instantly lifts and outfit and adds a touch of luxury to it (this one's Hermès but you can find a more purse-friendly version at Topshop). Suddenly your classic black skinnies and white shirt are that much more chic and interesting, and all it takes is that one simple accessory.
