All Hallows Eve

Today is Halloween. You, John Doe, are to be at a Halloween party tonight. However, you have forgotten to buy a costume. Upon realizing this, you rush to the nearest costume store. The limited selection is rather slim, considering it's the day of Halloween.

In the men's aisle there is only one costumes to pick: a vampire. However, feeling that perhaps you can find something in the women's aisle, you go over there as well. There are only three picks there: a vampiress, a devil, or an angel.
