So imagine with me that you're absolutely wacky, slightly off-your-rocker, but marvelously well-intentioned. You have longish blonde hair, brown eyes; you're midtwenties, and from the 1930s (though being "period-appropriate" is lower on my list of priorities than other things). You also have a VERY wide range of expression, from absolutely distraught to smug to pseudo-scary to ridiculously perky. If you can be described as "cartoonish," that is very much a plus. You also dress up in funny costumes from time to time.
Oh, and you also happen to be this gal. You're a RL version of the inimitable Miria Harvent of Baccano! fame. Who are you?
