Not a single clone I am aware of introduced himself as a number*. The clones also follow no visible fashion trend. They all go in their unique direction. This is a clear search for individuality and uniqueness. Which people in real-life also seek, true, but people in real life are usually not dehumanized the way clones are. Like if parents named their children "Child One", "Child Two", "Child Three" and "Child Four" what would that tell you about the way these people see their children?
*Except Fives, but even then, it's not his actual designation. And he's even the one who to literally say "I'm not just a number, none of us are."
