Once I dressed as a flapper for a murder mystery party I was attending. I was pretty proud of my costume from the neck up. I didn't have time to find a flapper dress however so a falsified a drop waist on an inappropriately long dress I had.
We'd all been assigned characters prior to the gathering and I was given a main role, for my overdramatic tendencies. I thought for sure I would end up as the murderer. It turned out I was innocent, but instead won the prize of best actress.
