Class isn't the only place you can take your backpack. Kate Bosworth  brought hers to lunch with her dad in LA, rounding out a polished and on-trend pairing with a cool-girl Alexander Wang  bag. We love a checked blouse, which already made us fans of her top, but when the style setter mixed the more sophisticated print with a pair of edgier leather shorts, she landed on a perfect mix that walked the line between buttoned-up and totally effortless. As if it couldn't get any better, she finished with a pair of walkable block-heeled ballet flats. Shop the easy combo right here.
