Are you looking for specific characters that dress as school girls?
Also, if all else fails, I guess an easy costume would be Misa [DN]
Not really, but I do like the Misa idea.
I thank thee, though I'm not very good at looking like a boy. I failed at L when I tried...
It's alright, Practice makes perfect. ^_^
I wasn't very good either when I first tried. I tried to do Itachi from Naruto when I first started out a couple years ago. I am happy that I didn't have any pictures of that horrid cosplay.
