Hi everyone! I will soon be going to an アニメ convention and I am wondering who to cosplay as who shpould it be? (info will be below) :)

I suppose Tohru would be too obvious

from Blech u could go as Orihime, Retsu Unohana(head of 4th division) または Byakuya Kuchiki

from Soul Eater あなた could go as Tsubaki または Liz

how about yuki from vampire knight

Well, I know that Black Butler cosplays get really expensive if that helps あなた narrow it down, and also the only brunette character in that 表示する that comes to mind is Paula, Lizzy's servant, who isn't exactly well known.
Vampire Knight, I suppose あなた could go as Yuki, but maybe あなた could try going as Ruka Souen, although her hair is fairly light and you'd have to find a way to make it wavy. I'd suggest braiding your hair when it's wet after a shower, that's how I'm doing it for when I cosplay Hungary from ヘタリア later this month.
Fruits Basket... I'm trying to think. あなた could easily go as Tohru, of course. If you're allowed to use temporary hair dye, try dying your hair black and dressing up as Isuzu. She wasn't in the anime, but any true Furuba ファン who has read the マンガ would be able to pick her out of a crowd.
Soul Eater, again if あなた can use temporary hair dye, あなた could probably go as Liz または Maka. Be warned, if あなた go as Maka make your own scythe, または find a Soul cosplayer to hang out with. The scythes they sell on the Internet get REALLY expensive. I'm talking $100-200 here. And if あなた go as Liz, either go with または find a Patty cosplayer and a Kid cosplayer. もっと見る people would take pictures if it's the group, and it's a good way to meet new people.
