The ivory set is, as others have noted, a pale buttery yellow, which is what I was looking for.  The fabric is very smooth and soft, but I have to agree with the reviewers who noted how thin it is.  I've uploaded a photo to demonstrate what I mean.  Obviously, any duvet you put into it will be all white and not have dark areas that show right through like the cover of the book that I slipped into the duvet cover; this is just meant to be a visual aid to help with understanding the weight of the microfiber used in this item.  It's pretty, but ...yeah, pretty thin.
