Tunic: COS
Trousers: Zara
Flats: ASOS (similar)

There's nothing like a COS sale purchase to put a smile on my face (I am happy, despite my resting bitch face). I snapped up this boxy grey tunic in the mid-season sale and it's proved to be the perfect piece for this time of year, especially when you're battling between the cold of outside and the heating in the office.
