In this comedy short, Roscoe 'Fatty' Arbuckle gets a fair number of laughs from a simple idea. He has to get himself ready for a formal occasion in the evening, and he finds himself encountering a series of unexpected difficulties in getting himself dressed. There aren't really any big laughs, but the movie is usually moderately amusing, and Arbuckle's timing is pretty good. The version of "Fatty's Suitless Day" (also called "Fatty's Magic Pants") that aired recently also had a catchy musical score that matched the action nicely.
While this isn't one of the best comedies of the era, it's worth a look.
