Public Nudity/A history assignment
Today was the day of an annual school tradition where all the history classes for each grade have an assignment due on the same day where the student's need to dress up for the time period they've chosen. Regardless of whether the students come to school dressed up or change once they arrive, everyone spends the day in costume in a sort of second Halloween.
Even if they have to give a presentation about their time period everybody looks forward to today, not just for the change in dress code, but because many students tend to wear revealing outfits such as loose fitting robes and togas.
Which is exactly what you have planned for yourself.
You walk to your closet where you've kept your outfit and throw open the doors.
What's your assignment and costume?
