I feel like some of these girls are cosplaying "scantily clad asian girl" :P Seriously, there's a chunk of these I don't think they're actually cosplaying a character so much as they went "I'mma go to comiket without pants!" Its not a bad thing it just amuses me xD
Holy shit I know that person at #50! He was in our tour group from Misawa! Too bad it was SO FUCKING HOT out I started feeling light headed from standing around taking pictures.
