We were super excited about this duvet (my boyfriend and I had been hunting for a while...), but overall we are disappointed and will be returning the product. :( 
The duvet is fairly true to the color (we got glacier grey), and extremely soft, however, the fabric is very thin. I don't know how well this will hold up in a wash. Also, there are faint brown ugly stains near the buttons, and for us, it does not look oversized. It fits like a regular duvet. *Sigh*
