Have mercy on us all. The Nun Adult Costume will put evil-doers in their place and take them back to Sunday School. Add an optimistic outlook on life and the will to do God's work and the gown will sell itself, turning you into the most proper creature in the bar. Carry a ruler in your back pocket for good measure and give everyone a scare. The wrath of a Sister is like no other, as far as knuckles are concerned.
