Master Bedroom

We just bought a new mattress set and now I want to do something new with the entire bedroom. It's one of the few rooms we haven't painted yet and I'm in the mood to gather ideas. We won't be buying new furniture (maybe a bed frame, eventually) and most of what we have is white so we'd be working with what we already have.
This montage by West Elm is pretty close to perfect for me (hello yellow and stripes!).
What are your favorites styles for the bedroom?

P.S. I don't usually shop at Sears but they are having serious sale on mattresses right now - might want to check it out if you're in the market for one!
