Well when I got this it was all wrinkled so I put it in for a rinse and dry. But the wrinkles were still there when I took it out of the dryer. I put it immediately on the bed and the wrinkles actually came out because it was still warm from the dryer. But to get that pleated look like they show you in the pictures I would have to iron it. Otherwise it is very nice. I think if they used a better quality polyester material there wouldn't be a wrinkle problem.
