This is an off-white cotton set from Peter Reed, a brand that supplies the British Royal Family. It was purchased at Harrods in London. It has been dry cleaned. Duvet cover size: Length: approximately 200cm Width: approximately 210cm Size of the two pillowcases: Length: approximately 47cm Width: approximately 66cm Simple lining goes all the way around, in a square shape. The duvet cover opening is buttoned. The pillowcases have a simple opening. As shown in the last photo, there are a few faint stains on the cover, but in my amateur opinion, they are not very noticeable. I used this set for several years, but it was used at a place other than my home, and it was one of several duvet & pillowcase sets I own. Please understand that this is a used item before purchasing.
