I love the size and comfort of these sheets!! Great quality. Unfortunately,  there was a weird factory smell to the sheets, so I  immediately washed them by themselves in cool water. I dried them, and the color changed. They went from the perfect grey to having a purple sheen to them. I compared them to another grey pillowcase I  have which is true gray,  and these are definitely more purple after washing. I still like them, so no problem!
