I have a friend who put together a Gaius cosplay this year. I'll have to see if I can convince him to come. I do know of one friend who is going as Florina from Blazing Sword.
Cosplays I'm currently working on:
Tear Grants-Cool Chick from Tales of the Abyss
Tsunade-Strength of a Hundred mode from Naruto
Tashigi from One Piece (either pretimeskip or timeskip version)
Nyna from Fire Emblem Shadow Dragon
The Shadow Queen-initial form from Paper Mario The Thousand Year Door
Lucina-Great Lord from Fire Emblem Awakening
