No, unfastening your button-downs to your navel (à la Cara Delevingne) will not work for professional settings, but there's no reason your 9-to-5 wares can't play hooky from the office every now and then. We all do it, so why not let our workwear in on the action, too? Plus, everything you need to recreate Delevingne's style is likely already living in your closet — though, we wouldn't blame you if you added Reiss' white, waffle-texture suit to your wardrobe. As for the blouse, any black oxford will do the trick. Pair with open-toe booties and an edgy ear cuff to finish off your badass look. All that's left now is to perfect your captivating stare.
