Corporate Goth can give you a hand.
What's your degree in? I'm fortunate enough to be in I.T., where certificates and degrees account for a big part of it. In fact, I've seen some bosses who were thrilled that their "goth" employees would actually wear a suit, even though it may look a bit on the darker side.
Edit: Oh, and location, location, location. If you're in a small, rural, conservative town, then chances are you're not going to be able to get away with a lot. Usually if you move to a larger, more liberal city (Like San Fransisco) you'll be able to get away with a lot more.
