I purchased a king size cover for my new queen sized comforter and the fit was just slightly larger than the comforter but that is OK as I have't had a chance to wash it yet. The color and fabric were beautiful however my only complaint is that shortly after using the shams I noticed a bleach spot on a sham and didn't know where it came from. Slowly more started to appear on the shams. ( I did not use any sort of bleach product in the wash, just regular detergent) The only thing I can think of is that it came from cleansing products I use on my face. I use the Clinique 3 Step system regulary and Bare Minerals make-up. It may have come from the toner I use on my face before bedtime. Sadly, I ended up having to throw the shams out but the duvet hasn't shown any marks. I haven't had this experience with any other of my pillowcases but I just thought I'd give everybody a heads up.
