Here’s the thing. The coconut buttons on the top of the duvet cover are NOT functional. They are attached to a loose strip that wrinkles VERY easily and you WILL have to iron it to get it straight every time you wash it. The coconut buttons on the pillow shams ARE functional and they are great! If the duvet cover worked the same way it would be wonderful and 5 stars, but the button closure is actually underneath the duvet cover and they are clear buttons there. If you have the time to iron every time you wash, it’s 5 stars for sure.
This is a nice duvet but be advised when it arrives in the package it is terribly wrinkled. The care directions state DO NOT IRON. Therefore I washed the pieces on gentle cycle and low heat which worked fine and most the wrinkles were gone. The exception was the “button bands” on all pieces. I gently ironed those. The fit on our queen bed is not quite wide enough (side to side) however we have a thick mattress. If it had fit the bed better I would have given it an additional star.
