I purchased these pillow cases along with my stone cottage duvet. I have a king size bed, so the pillows look a little out of place. This would fit better on a queen size bed. The color of these pillows match up exactly to the flip side of the duvet/comforter. I don't know why the title describes the pillowcases as sateen. That is not accurate. I would say this is not needed as part of the whole set.
