I ordered the duvet cover, flat sheet and pillowcases in the same series and the same color. I followed the advice shown on the packaging, namely wash at 30 degrees before the first use ... So I washed all together. As a result, no two things in the same color ... The sheet turns pink gray, the duvet cover was thinning, and pillowcases remained dark gray ... So it's ugly! Oh and the cover does not 220x240 despite what written on the packaging, so too small for my new quilt! I recommend you to choose another collection!
