You know you're a cosplayer when...
The first thing that comes into peoples' minds when they first walk into your room is "SHE'S A MASS MURDERER" due to the row of heads sitting on your desk.
You look at an official figure and point out the inaccuracies in the costume.
You have to run a magnet over your floor before vacuuming to check for pins.
You have a single costume that takes up more room than your bed.
You remember exactly what that particular character was wearing down to the lapel pins, but can't for the life of you remember his/her name XD
Opening a cosworx wig box is like Christmas morning.
