Clean Looking Beach Themed Room?

Hi(: I am redoing my bedroom tonight, maybe tomorrow, and I wanted a neutral looking room. I'm 14 and I was thinking something like a Beach or Spa themed room. I wanted to do like a teal and white color, or maybe a medium brown and white. I have white washed furniture, dresser, bed, and desk. My rooms average sized and I have one small window and beige carpet. I want it to be clean or fresh looking. That should be it, but any ideas as to what I should do or put in my room? What colors? What accessories? Thanks(:
