In the first look, she paired an olive button down with some skinny blue denims and wore gun-metal patent heels (possiblly YSLs). She was also carrying a pistachio coloured Balenciaga bag.
Those bright yellow flats really add a punch to the otherwise neutral looking second look, I also like her fitted grey trousers.
In the final look, she wore a leather jacket, with an Alexander McQueen skull-print scarf and added some delish green drop-earrings to the ensemble
