Question: what is the difference between a duvet and duvet cover?
Answer: In the United States, many call the Duvet Cover a Duvet. Regardless, it is the decorative covering that goes over your Down Comforter to protect it from body oil, dirt, make-up and other things that might soil it. Think of a Duvet Cover (Comforter Cover) as a large Pillowcase for your Down Comforter.
