Just take a peek at Reese Witherspoon's Instagram account, and you'll be instantly flooded with pictures packed with her three darling children, her best celebrity gal pals (Nicole Kidman and Jennifer Garner, anyone?), and her collection of ultra-flattering dresses from her clothing line, Draper James. Our favorite Southern belle knows how to rock a floral fit-and-flare like we've never seen, and she just took over our spring and summer outfit plans with a shirtdress that strikes the perfect balance on the cute-casual scale. During her spring vacation with sons, Tennessee and Deacon, and husband, Jim Toth, Witherspoon gave us a glimpse via Instagram with butter blonde hair flying, adorable son dancing, refreshing drink flowing, and big smile beaming—all in that perfect navy floral number.

The dress in question: Draper James' Belted Daisy Vine Shirtdress. And it rings in at only $98. (Find it here.) It's the kind of dress you can wear literally every day. All. Season. Long. With its great neutral navy base, subtle floral print, flattering belted silhouette, and classic above-the-knee length, it checks every box for the perfect warm-weather dress.

Witherspoon paired the look with strappy flat sandals, but as per the clothing line's styling, it looks just as great with chic white sneakers too. Switch your casual shoes for summery espadrille wedges, and you've dressed it up faster than greased lightning. You can find the navy floral pattern in a V-neck popover top as well, which happens to pair just perfectly with white skinny jeans. ($48; We'll take both, please!
