Everyone has their own style, but you need to be careful about how flamboyant and "out there" you are at a job interview. You don't want to be disqualified from the process because your potential boss thinks you look weird.
Avoid wearing large pieces of jewelry or heavy/unnatural makeup to an interview. These may distract the interviewer and, thus, detract from your performance.
You should also avoid wearing cologne or perfume. The interviewer may not only find the odor to be distracting or offensive, but may also be allergic to the ingredients.
