This duvet cover is AH-mazing. The duvet cover doesn't have additional clipping to secure the duvet inside of it besides the outer buttons on the 1 side but it stays in place extremely well. This has got to be the softest cover I have ever had. I purchased this along with the 'midweight all season down alternative comforter'  from Wayfair and together they feel like a hotel comforter. I've never been this excited about a set before and look forward to going back to bed later.
