What a great thread. Your style is gorgeous, no doubt. However I understand you want to explore.
1) First, lots of pics is a great advice.
2) Then, set aside some time, go to nice stores you like and just try on different items: shapes, colours and items you would normally never wear. Make it a point to do so. Don't buy anything (unless you completely fall in love). Revisit the pencil, for example, because they keep coming up with new fabrics and better cuts. I could see you in a long midi-length pencil for example, an A-line long jacket, wider, fluid pants, silk print blouse...
3) Then, pay special attention to the shoes/booties. They make or break a style. If you find yourself constantly wearing the same types of things, it may be because the footwear you have command it. Study other styles, and pay special attention to the footwear.
4) Try different ways of tying your scarves. http://www.youtube.com/watch?v=5LYAEz777AU
