ACEN poll!

Alright, so I've been AWOL again for a bit. And, again, I apologize. Lots of things have happened, some good some bad, and I really should blog about them. But today, I am blogging with a mission, albeit a selfish one. I realize that most of my blog-readers are also my FB friends, but there may be a few new visitors because of FB. That is my hope, at least.

Here is the gist of it all.
Near the end of May I will be attending ACEN, an anime convention in Chicago. It is 3 days long.
Here is my dilemma, and the poll I ask all of you to participate in. I have 4 costume (cosplay) ideas in mind, but 3 days. Here they are:

Generic BLEACH character:
For this I already have the costume, minus the division arm badge and appropriate shoes, though I have shoes I can wear.






Generic Japanese schoolgirl:
For this, I have a white shirt, black tie, black skirt, etc. for a general costume.

Hirasawa Yui from the anime K-On!:
For this, I really don't have much, other than the same white shirt from the schoolgirl outfit. Some of this should be easy to find, though.

And last, young Hungary from Hetalia: Axis Powers:

(She is the one in green, with her hair pulled back)
I also do not have much for this one, but Items can be procured or made.






So, there you have it. 4 ideas, 3 days. What should I do? if I do 3 different ones, which 3? Or should I just go with the ones I already have, and forget about the others? These questions need answers, and so do I! Please, give me your guidance!!
