Mizuki Kishikawa, the creator of the series, said in an interview that character outfits can help reinforce a story's setting and characterization. Since the story focuses on university students, Kishikawa needed to constantly design casual outfits. Although Kishikawa initially struggled with drawing clothing, they improved their skills through consistent practice with full-body illustrations. When creating the characters' outfits, Kishikawa usually first chose one or two items they wanted to draw, then built the rest of the outfit around them. They generally selected clothing based on the style that they felt would best suit each character, and would often reference brand lookbooks featuring those styles. Kishikawa also drew inspiration from music videos, magazines, and outfit of the day posts on social media. Accessories such as bags were varied less; Kishikawa felt it would be unrealistic for university students to own too many. Because the series is primarily drawn in black and white, Kishikawa sought to balance each character's design so that it was neither too dark or light, such as having darker-haired characters wear lighter-colored clothing on their upper bodies. For the full-color illustrations accompanying the series, Kishikawa avoided color choices that clashed with the characters' natural traits, such as their eye colors. In addition, Kishikawa incorporated color combinations that were fashionable at the time, which they did by checking recently released clothing and store displays.
