You always enjoyed wearing costumes on Halloween especially when you were an adult, because when it came to a night like the one you celebrated, you could just pretend to be someone you weren't. When you were little you use to dress up, then go door to door while trick or treating for the candy they had.
Now you were a teenager, and you had some friends who were throwing a Halloween party which was going to allow anyone who was in costume as they served food to anyone there. Dressing up in a costume was a little like getting into character to do a movie, especially when it also involved the makeup some people wore. While you were in the aisle, you saw that there were so many costumes, and makeup that you couldn't exactly know what to get, and needed to hurry too.
