I really agree with the poster who mentioned style being important. A great resource that I discovered a few years back was style-forum (www.styleforum.net). An old Prof used to call me Thoreau because it apparently looked like I had just stepped off Walden Pond, but I have made a lot of progress in the last two years thanks to advice I picked up off of there. Just lurk in there and observe what styles you like best (street style, mens casual, etc) and go from there. Personally, it has made a big difference in my confidence and you start to notice that people do treat you a little bit differently.
