Mini bags have been relevant for quite some time, but Kate Bosworth's Rochas crossbody takes the trend to a whole other (smaller) level. Paired with a crisp, white Totême shirt, Citizens of Humanity jeans, chunky heels and sunglasses she co-designed by Jacques Marie Mage, the actress brought the perfect-for-an-evening-out accessory down to a more casual altitude. Aside from being the cutest bag trend of 2017, these micro minis really make you redefine what counts as an everyday essential.
