Eeeyup, I cosplay at a London convention twice a year. Thus far I've done:

Nightingale Armour - Skyrim
Touko/Hilda/White - Pokemon
Team Magma Grunt - Pokemon
Cynthia - Pokemon
Marceline - Adventure Time

I'm currently putting together Serena from X&Y, and have plans for Officer Jenny, May/female RSE trainer and Daedric Armour from Skyrim.
