The routine takes place on what looks like a circus stage. There are multiple spirals on the floor that starts out pink in the bridge but turns red during the chorus. During the rest of the song, it is purple with blue circles. When the dancers move around the stage to change positions, the spirals move with them as well. The platforms behind the dancers also light up sometimes in tune with the beat. Flames can be seen in the background when the word "Circus" is sung in the lyrics. At the same time when it is said, the very back of the stage lights up to reveal the word Circus.
The routine takes place on a stage with several red lights which can be seen throughout most of the verses. The background also changes to pink and fuchsia with the addition of some pink smoke. During the chorus the stage becomes red with a triangle showing the dancer performing in the middle.
