Dresses, meet your match. The Essential Cashmere Crewneck Cardigan is the perfect proportion to wear over fit-and-flares and sheaths alike. With its slim fit and high-hip length, you can even try it buttoned up over loose pants for Katharine Hepburn flair. We love this sweater as a topper for cocktail dresses when you need a little bit of extra warmth but don't want to add any bulk to your outfit.
