I've done quite a few cosplays before. Now listing them all in chronological order...

-L (Death Note)
-Grell (Black Butler)
-Italy (Hetalia)
-Operation Anime agent (OC)
-Missingno (Pokemon) 
-Crona (Soul Eater)
-River Song (Doctor Who)
-Adric (Doctor Who)
-Ed (Cowboy Bebop)

Or at least, I [i]think[/i] that's all of them... I feel like I'm missing some. Hmm...

Unfortunately, I'm severely lacking on pictures. 

I might come back to this thread to add those in for any I can find.
