Mummies. Vampires. Ghosts. Frankenstein. Ghouls. Zombies. Witches.
These are what I think of when I think of Hallowe'en. All Hallows Eve.
Superheroes and princesses, in a pinch, though they pander to stereotypes.
Sexy nurses, sexy firefighters, sexy nuns, sexy ebola doctors... WTF???
Sexy ANYTHING is not Hallowe'en.
My daughter knows. She does her own makeup.
