If there's one style lesson we've learned from this year, it's that flats are very much back in style. Take Michael Kors' Mathilda Flex. Crafted from soft and flexible leather, this design's square-toe silhouette features dainty straps that delicately buckle shut. Of this, we're certain: whether you're attending a formal event or simply grabbing brunch, these are certain to perfectly pair with any ensemble.
