Everyone dies for Isabel Marant but her younger, just as chic sister label serves the same purpose with each new season. For fall I'm digging the classic wardrobe staples with a twist. I've got a closet full of button-downs but none with Victorian ruffle detail like this one. Worn for fall with sleek black denim and oxfords (or better yet, penny loafers), this shirt is a dream. Naturally, Isabel Marant continues to redefine what's cool.
