This comic follows right after the last one. Risa reveals her costume to Terry. She’s never worn anything overly feminine before. That actually comes as a shock to Terry, who’s never seen Risa outside of her usual practical attire. Upon sight, it probably took Terry a couple of seconds to realize the person in front of him was Risa.
Olivia’s costume design was just one thing. I’m pretty curious to see what else she can do and how much she can influence the Yogurt cast over the next couple of years.
