If I can say only thing, it's this: JOB INTERVIEW TIME IS NOT THE TIME TO SHOW WHAT YOUR MAMA GAVE YOU. That (a) won't get you a job, (b) may keep you from getting a job you otherwise would have, and (c) will get you a bad reputation.
DON'T DO IT. Save your dignity and keep those skirts knee-length and longer, even if that's not at all what you normally wear. I have nothing against your legs, but they probably shouldn't be on display when you're trying to be taken seriously as a young professional.
Also, don't go for your crazy high heels, enormous costume jewelry, or bright eyeshadow. Remember that you're outfit should be more or less neutral and you should be the one standing out!
