I LOVE my duvet cover! I chose the grey door which is a light concrete grey color, then i got darker sheets and the contrast is beautiful. The duvet is so lightweight, so you can adda a heavy or light comforter inside to make it as warm/heavy as you'd like. Also it's so soft! two thumbs up :) 
I was hesitant to purchase because it was so cheap, i thought the duvet wouldn't be of any quality...i was wrong! I also washed/dried it and it held up just fine. I hope it lasts me for years to come, i have already recommended it to friends and have been bragging about my purchase.
