This right here is the essence of why I love this show. It's a makeover show, but it's not just about telling people how they should look or eat or live and making them conform to it. The Fab Five really do focus on what the person needs and what is going to work for their life. Tan doesn't tell Joey that he needs to shower every day, because the fact is, Joey's not going to do that. It's not something that feels good to him and it's not practical for his life. Furthermore, telling someone to shower more isn't actually helpful, it just makes them feel shamed.
Instead, Tan gives Joey ways to stay fresher and cooler without needing to shower more often. He's not trying to change Joey's overall behavior, he's trying to give him clothing that suits that behavior. It's not about dressing how he's "supposed to," it's about dressing in a way that works for him and makes him feel better.
Plus, like, when Joey cares more about taking care of himself, he'll probably shower more often on his own anyway. If you can get him to care, the rest will follow.
