Hetalia Cosplay Reccomendations?

[hearthem.livejournal.com]

So I guess you could say seeing all these Hetalia Day pictures has made me more interested in Hetalia cosplay.  Trouble is, it's hard for me to decide [as you know, so many characters!].  Now, if my parents were normal, I'd probably just go as one of my favorite characters or what not.  But there's a problem.
My mother only allows me to cosplay female characters.


Now of course, they don't have to be 'female', but they have to look enough like a girl for me to get the okay.  [For example I have a chibitalia cosplay, and my sister has the trap!ciel in a dress from kuroshitsuji].

Here's some of the costumes I was thinking about:
France from Austrian Succession
Pirate England
Female Sweden [Just Sweden with long hair?]
Female Canada
Female England
Monaco
Belgium

What do you guys think?  I want to do something special, eg, not just Hungary.

---Thank you so much for the help and all that jazz, everyone!  So helpful, I wish I could repay you ;w;---
I've gotten a lot of suggestions for Monaco, Belgium, as well as many more!
