Kristen Stewart has been turning it out on the red carpet lately, using her On the Road promotional tour to reassert herself as a badass glamour girl. Last night at the film's NYC screening, Kristen showed up wearing a look that basically solidifies our belief that a crisp white button-down blouse can work anywhere, even at night. She layered a slouchy gray tank with a Balenciaga top, then tucked both into a loose-fitting pair of black ALC trousers. She finished the laid-back look with simple gold jewelry and a striking pair of Jimmy Choo cage heels. We're in love with her ensemble, mostly because it serves as proof that a) black and white are a classic, no-nonsense color pairing and b) you should never think twice about rocking your workday essentials after the sun goes down.
