new full duvet cover

For a pre-teen girl who is into color combonations such as:scarlet red or a sharp red with orange and a light or pure yellow. She also wants her duvet cover to have those colors be polka dots and the back ground white.Another thing she would like is green and blue and any other color that goes with those well. My middle school daughter also likes stripes.If you have a full duvet cover that is new and fits my descriptions let me know. Thank you for your time.
