Reinventing your style can be the hardest thing to do but if you plan on doing so always start the process slowly. For example if your current style is a preppy look and you want to be more edgier start with the basics change your regular jeans to leather leggings or wear edgier accessories. Once your out of your safe zone then you can begin experimenting more with your look. The last thing you wouldn't want to do is confusing your peers with a sudden new look. Always start slowly and gradually get to your ideal style in due time you will be satisfied and people will also take notice.
