In every episode, Pops wears the same (or similar) outfit.
Pops wears a black, small top hat on his head. He wears a black vest with a white, long sleeved shirt underneath it. He also wears gray pants and black shoes.
In "Rap It Up", Pops wears an red hoodie, with a blue baseball cap on, with white tennis shoes and wears gold chains. Later in the same episode, he wears a lime-colored vest, with black outlining and a white tie, which Mordecai and Rigby think is "lame". Also, in "Dizzy", Pops was covered in marker by Rigby, so Rigby created a face on the back of Pops to make it so Pops could give his speech. In "See You There", Pops wore a costume of an ice cream cone and soft ice cream.
