[It's objectively still a shirt (and suspenders, jeez!!), but now that Junpei has the forbidden knowledge that Charles is always wearing way too many layers (like someone who knows how to dress, go figure), the tank top is so... Well, his mind has assigned it a critical level of importance, and he's doing his damnedest not to linger.

Lucky then that he has the yukata to occupy his eyes and hands with. He scoffs lightly, as Charles says that at the precise moment he's noticed he did these steps in reverse because he was thinking about how it would look to put it on himself, so hang on, he has to start over.]

I'll know. And so will people at the festival, so just- hold still.

[He's folding, he's draping, he's idly wondering if they should have stopped to pick out an obi Charles liked instead of just the one that was paired with this yukata, but Charles said don't worry about the patterns, hmm... It's another few moments of quiet, which he finds to be pretty cozy and comfortable despite his fumbling. Hmm...]

You gonna remember how to do this? I know you don't have to, but... [well, since he wanted the experience...!]
