I've never had this problem, but I frequently switch friend bases and generally make friends fairly easily. My advice is just about the same as anyone elses; be yourself. It's corny as fuck, but true. If you start acting like some really cool badass, people will notice, and you'll only dig yourself in. I'm sure that you've seen people try to hard to fit in even on these forums, and ultimately they are rejected. Join clubs, play sports, and most importantly DO NOT expect people to come to you. You must be extremely social, find common interests, and exploit them in your conversations to find new friends. Attempt to be funny, but don't just say stupid shit. The only thing you can do past that is dress nicely. If you are dressed in a very nerdy way, people will treat you like that initially and will only forget it once they get to know you. However, if you are "trendily" dressed, people will feel much more comfortable with you. Once you finally "fit in," then you can become a trend-setter and make your own styles that will gain popularity just because you are wearing them. But, for now, normality in dress is something you should strive for.
