I guess I just never really grew up.
I played dress up as a child and as I grew, so did my wardrobe. I've been acting/modeling on and off since I was 16; and I always feel right at home in the skin of another character. I enjoy costumes of any sort, so just sort of fell into cosplaying as an effect of that. Now, I'm a new mommy, so I get to spend some extra time doing some baby cosplays :)
