I ordered a king size for a queen bed so it would drape over a lot. That went great. I ordered the white - it’s a truly bright white, not ivory or off-white. It has ties in the corners to keep your comforter lined up. The king comforter I use is a few inches longer than the duvet, so it doesn’t fit exactly, but better that the comforter is too big than the duvet cover, if you like a bulkier, filled look. The ruching helps to accommodate a bigger comforter because the top ruched side expands a tiny bit. The comforter must be white, though, or you will see the color through the duvet. The matching shams are sized to match the duvet size, so I need to get some king pillows to fill mine. Standard pillows would probably only fit the twin or double size. Overall this duvet is a beautiful way to add some texture and interest without being too busy!
