These curtains are modern looking and elegant. The thin silver geo pattern is definitely shiny silver but it's very subtle when the curtains are hung. The black out feature would definitely make the room dark. I ordered extra sets in anticipation of having a seamstress make two cornice treatments to match the curtains, however the fabric is 100% polyester and the hand of the fabric just didn't work for my project. I returned and ordered another pattern in a cotton/poly blend, but I would highly recommend these curtains if you like the look!
