Depending on the role you are going for, choose your interview attire carefully. Even though you may have a personality which is larger than life (with the wardrobe to match), try to dress conservatively, at least for the first interview so that you can gauge the type of working environment that your prospective role will be in. No matter if its business casual or full corporate dress, make sure your clothes are clean and tidy - people often make subconscious judgement's based on appearances, so you want to do everything you can to impress and one of the easiest ways to show your professionalism is through what you wear. Dressing for success will not only give a great first impression, but will also bolster your confidence during the interview.
