Technically, the closest thing to cosplaying I did in the past was a half-assed Bellatrix Lestrange outfit I threw together- which was last year. My two Friends also attempted to dress like Harry Potter characters (I was the only successor)- one was Luna, other was Hermione.
..Hopefully this an ou suivant I can at least manage to be L (Death Note) ou Akito Sohma (Fruits Basket), since they're the easiest to cosplay for a newbie.
