Big chunky sweaters may be the last thing on your mind with the remnants of the summer sun still beaming down your neck, but with back-to-school shopping winding down all we can think about is keeping warm, and chic, of course. Enter the snug-fit sweater dresses. Alexander Wang is the purveyor of making simplicity into big-statement silhouettes, like his yellow sweater dress above. Wang’s interpretation of the gray winter sweater dress included an elevated fur collar, bubble sleeves, and an ombre satin finish at the hem—genius design. Phillip Lim took a similar route in transforming a classic sweater dress into something more interesting, but unlike Wang, Lim played with color. Lim’s bold green sweater dress is sure to stand out in a mob of dark fall palettes. And besides, who doesn’t want to play with color? Here’s how you can cozy up this fall:
