Wonderful Kingsize duvet cover! The midnight blue is really almost navy, but richer, unlike cotton which tends to look rather dusty in comparison. The bamboo has a beautiful silky sheen - and that's exactly what it feels like. Before my order I had some friendly and helpful phone communication to establish when the colour would be back in stock. It wasn't long, and after ordering it arrived in no time. Another review bemoaned the white zip, but they have now rectified this and ours was navy. The zip is quite soft and pliant and so much less fiddly than other closures. A perfect order!
