I was under the impression I was getting a 100% cotton duvet cover. Why then does it say 100% microfiber on the label?? I called Wayfair and talked to Patrick.  Although there was nothing they could do about that, (the label) they are now notified and Patric gave me the option to send the duvet cover back and get a full refund or keep the duvet cover and get a discount. I really like the product and I am hoping that the label is just a mistake and that it really is cotton.   Interestingly, the label on the pillow covers does say 100% cotton, just not on the duvet cover.
