Wow.. awful. Do yourself a favour and don't buy it. Marble is meant to look aesthetically pleasing but this looks like a thin, poor quality white sheet that's been chucked in the wash with black socks and turned into a horrible two-tone grey. My Primark bedsheets are amazing quality by comparison, and that says something. The black side looks less ugly but doesn't even slightly have a marble effect. Yikes. Returning it asap, if I could give it -5 stars, I would!
