With the move toward bell-bottoms and '70s flares, it's a nice change-up to see Jordana Brewster sporting the slim style we've loved for seasons. Even more classic is her button-down, tucked in, to take the denim from casual-wear to event-worthy wear. Really, the style isn't exclusive to skinnies; in fact, if you tuck it in to high-waisted flares you'll achieve the same clean look — and a flattering waistline. Face it, mom was right, tucking it makes you look way more put together. Just shop any of my button-down picks below to achieve the style, and feel free to mix and match with the denim you wear best.
