When it comes to duvets and comforters, you’re bound to be cozy curled up under either one. Duvets, however, offer more options because of their covers. Duvet covers wrap a duvet insert, keeping it clean and well-styled; to update your look, simply pick a new cover. Plus, they’re sized to fit with minimal overhang, giving your bed a modern aesthetic. These covers are easy to wash, too, as they fit into the machine along with your sheets and pillowcases. Sold? Try this damask set on for size: it includes one duvet cover and two shams (one sham for twin sets).
