I've been cosplaying since 6th grade. My first costume was Sailor Chibi Moon.
I have recently gotten into Gothic Lolita and J-Rock/J-Pop music costumes. Especially Aya's costumes from Psycho le Cemu!
It's really hard to say where my insipartion for my costumes comes from. Nowadays it's mostly because of my friends and all of the cosplay groups I'm part of.
