What should I take to GMX?

I really have no idea what to take with me to GMX.
I’m definitely taking Wasp, because I’m finishing the wings, and Marie Antoinette TARDIS to go with my cousin’s 11th Doctor costume.
Thinking about taking Anne Boleyn too.
Otherwise, I’m thinking about:
Time Lord
Donna Noble
Batgirl
Emma Frost
Jane (Tarzan)
beyond that nothing is really saying “WEAR ME!”
So I’m open to ideas…
