I expected, for the price point, that the duvet cover would have a zippered closure. It doesn’t.  It also doesn’t come equipped with corner ties for your duvet. The comforter set is much nicer, if you are undecided between the two (I bought both, for winter and for summer). We’ve been using the duvet as a throw blanket more than anything, and the duvet does move inside...next time I launder it, I’ll be sewing in corner ties to keep the duvet from sliding to one end in a bunch!!
