My Grandson went as a gangster two years ago and it didn’t seem odd at all. He went as an angry bird last year. It looked awful and his Mother tried to talk him into something else but he insisted.
I think my Granddaughter goes as a princess every year.
My six-year-old nephew went as The Gangster last year (Number 19 in that photo gallery). Without the toy weapon, of course. Cheap little polyester business suit with fake shirt and tie, and a cute little cardboard fedora. She bought it at WalMart, and it even came with black mustache paint. My sister drew a goatee on his face. He left home with seven other neighborhood children and two teenage chaperones. The only reason the teens agreed to guard them through the neighborhood is because they wanted some free candy, and they were too old to trick-or-treat. Teenagers in my neighborhood beg for little kids to take trick-or-treating. That boy came home with two plastic grocery bags full of candy. His momma and daddy ate most of the good stuff, and by December they wound up throwing the rest away.
