The material does not match the same company's pillow cases in the same color, white, and 400 thread count. I liked their pillowcases, so I bought the fitted sheet to match--but it didn't match. The fitted sheet was a pinker white, rougher, and felt as if it has polyester mixed with the cotton. I thought a wash would fix it up, so I committed and washed it, but it did not help. These are not sateen, soft sheets. They feel like they are ready to pill. I would look elsewhere for a fitted sheet.
You can see in my photos the difference and how the fabric looks scratchy and like it's ready to pill.
