You've made it this far making your own decisions (for the most part). By now, your own base instincts have led you to a point in your style where you're comfortable. Your style has been tested, failed, re-tested, and mastered all on your own (most likely with the help of magazines or the Internet.) You want to wear a noragi? Wear a noragi. Want to throw on some Birkenstocks? Nobody can tell you to do otherwise.
