/cgl/ - Cosplay & EGL

After going to A LOT of cons with my friends and not doing anything fun or wholesome since those retards refuse to meet new people or even cosplay, I'm going alone to the next local con and I'm quite nervous. It's also the first time I'm cosplaying in public and I don't want to look like a retard, just make some friends with the same hobbies as me.
Any tips?
