What would you like to see people cosplay?

Me and some of my friends are big fans of cosplaying. I've been doing it for almost 5 years now. for the past 2 conventions I've tried in my own way to be unique from the crowd because theres nothing more lame then cosplaying a main character and seeing 10 other people cosplaying the same person. Last con we did a firefly cosplay which was fun because no one else had done a firefly group, and the year before that we did a fma cosplay but I made myself different by actually making Ed's automail.
However,.. this year idk what I want to do, so I thought I'd ask you. What anime would you like to see cosplayed well that you hardly ever get to see? :) Thank you
