Be a man, be comfortable in your own skin, and make your own damn decisions.
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.
