This was one of three sets, each from different brands, that we purchased for a new winter weight, oversized king duvet (114" x 100".) The description says it's a couple of inches smaller all around, but, happy accident, those few inches mean that there are no skinny edges and it just fits beautifully. 

I washed and dried everything before I used it according to the instructions - in cold water and on low heat - and I had no issue with pulled seams or shrinking. Any wrinkles smoothed right out. 

The material is a nice, soft cotton, and it doesn't collect and hold lint. The stripe is much more pronounced than the pictures. I forgot to take a picture of this one when it came in, but I'll edit my review to add one the next time I switch out my cover. I'm completely happy with this purchase.
