Most Helpful Guy
Men and women are fundamentally different when it comes to clothes.
For women, clothes are like decorative objects that can be switched for another day by day. Like, "I want to look like whats-her-name today, then tomorrow, I'm going to look like that-other-girl, and then..."
For guys, clothes are more permanent and are intended to reflect his identity. Like, "This is WHO I AM today, then tomorrow, this is still WHO I AM, and then..."
Trying to get a guy to fundamentally change his fashion sense is like trying to get a gay guy to put away the rainbow stickers. Good luck, because you're going to need it.
