You cannot wear a top hat that obstructs another patron's view in a theater.

The Law Explained

Great Falls city codes once took aim at the fashion trends of the late 19th and early 20th centuries by banning tall hats in theaters. If your top hat blocked the view of the person sitting behind you, you could be fined or ejected from the venue. It was the historical equivalent of telling someone to put their cell phone away during a movie.
