This duvet cover fits very beautifully. It has good inner corner ties to keep the duvet in place and it has a button closure that actually folds over so as not to be directly visible. This makes it better for longevity, seeing that buttons often ripe off, so I appreciate this feature. Im not fully convinced that this is 100 cotton though. The texture of the material is not very soft, but instead slightly rough. Overall, not the worse buy, but not exactly what I was hoping for either.
