I am moving in October and I want a fresh start. I want my room to have a theme. Since we are living on the coastal, a nautical theme is obvious...but I'm one of those people that turns my entire room into a giant collage. And I keep room very, very messy. I want a room that's mature, as I am 25 years old, and I want my room to feel very grown up but also feel homey and like my own but still organized and not messy. How can I pick out a theme for my room?
