Drawing inspiration from a line in the play describing San Francisco as a "sea of checkered shirts" and the Walkers artwork series by visual artist Julian Opie, the costume design features graphic silhouettes and colour-blocking, capturing the essence of briefly observing passersby in urban settings without fully absorbing their appearance. The colour palette, informed by urban photography of San Francisco's landscape, further grounds the costumes in the play's setting.

Notably, the contemporary-set costume design was realised during a Level Three COVID-19 lockdown in Melbourne, Australia, with brick-and-mortar retail closed to the public, requiring adaptability and resourcefulness to bring the design to life under challenging circumstances. A design highlight was the costuming for Renaldo, a young professional with a secret alter ego as a furry, Cody the Coyote. The realisation of this costume involved complex costume-prop construction, including soft sculpture headpieces and a body suit.
