Here's the French-Girl Formula for Styling Mary-Jane Shoes

You don’t have to be a math genius to figure out how French women have perfected the outfit formula. When the goal is effortlessly chic, a wardrobe of staple basics can be mixed and matched to achieve a look polished enough for any event but easy enough for every day.

Case in point? Michelle Williams. The Montana native and noted fashion aesthete was spotted wearing our favorite outfit combination of straight-leg jeans, an oversize blazer, and Mary-Jane flats in New York City. The four-piece look, complete with a strawberry-red lip, was polished enough for Williams’s morning TV appearance and perfectly practical for running around the city now that it’s officially springtime. Even better, you don’t need a Hollywood stylist to re-create this outfit at home. Just grab your favorite blazer, jeans, flats, and button-down shirt. Roll up your sleeves, swipe on a bright lip, and you’re good to go. Easy enough, right? Oui!

Don’t have these basic outfit building blocks in your wardrobe? You’re in luck. We’ve pulled several pieces that can be combined to create the perfect jeans-and-flats outfit formula for anyone who wants to take French style for a spin—no passport necessary.
