I want to re-do my room, but I have no ideas!?

I'm a teen girl and I want to re-do my room. Right now, it is kind of a "parisian" theme, with black creme and dark red accents. I want to re-do it and make it something sophisticated and not too girly. My vision right now is all white furniture and all white bedding with a crisp, fluffy down comforter. And then a ton of jewel-toned throw pillows. And then colorful, quirky accents like tea-pots, vases, flower arrangements, mirrored chests, and paintings. Any ideas? Please help. I'm so confused
