Lol I'd be perfect.

It'll be great :D everyone would think I'm moony oh cool

Of course, it would be a blast.

Severus (even if I'm a woman but under all those dark layers of black fabric... who could tell ? LOL). I am usually cold at first sight, so that won't be a big change !
Or Bellatrix. I'm mad enough to play in a completely demented fashion to picture her adequately.

I was actually cast as Hermione in a Harry Potter play I was going to do with my local drama group. Sadly, we never got round to performing it (because our Harry left the group)!

I already have the look of Hermione. :)

Or Luna 'cause I'm blonde!

Luna because I'm SERIOUSLY strange/special as well;)

For sure!

I could play Hermione very easily because, according to my friends, I'm exactly like her. (I'm intellectual, rule-oriented, somewhat bossy, and rather badly bushy-haired. And I'm CONSTANTLY scolding them for their lack of interest in schoolwork and rule-following.)

Or Luna. Either one.
