Bought 2 dark blue for twin beds and they look good with my blue and white quilts covering the beds. There are some wrinkles in the cloth due to packaging which may relax with time. but don't show much due to the dark color. I did find any defects in the stitching or fabric on the items I purchased. A note for prospective buyers is that the dust ruffle covers the entire bed foundation, so get help to put on under a heavy mattress.
