Super Soft Down Alternative Comforter

I ordered the king/cal king. Which according to the measurements should be 104 x 88. Washed and dried per instructions. We just went to put it in the duvet cover and could not get it to work. I took it out and laid it flat on the bed only then to notice it has like zero over the sides coverage. I got the measuring tape out and it measures at 83 inches wide. Not 88. Measured the length at 90 something inches. We washed on cold, dried on cool, removed promotly. What do I do with this now? It’s too small for a king duvet and too long for a queen duvet.

I recently bought the king/California king comforter and when I received it, it’s the size of a twin comforter. It’s very narrow. The packaging all stated it was the king. So if you’re looking for an oversized comforter, this isn’t the one.

Where is my order? Paid for 10 days ago. It is 12°
