How can we make Teens stand out?

I'm on the fence with the teen-specific clothes and the clothing filter. But I do agree about the voices (though I think that the game could use a lot more voices in general).

If it were my job to "fix" them, most of my plans would revolve around animation work. I need a way for teens to be immediately identifiable as teens, even from a distance. Giving them their own walk styles, standing animations, idle animations, etc. These don't all need to be huge changes, sometimes little tweaks work fine (like the way teens kiss slightly different than adults do, it's a cute little detail that makes a big difference in how I perceive them)

In terms of gameplay though, I don't really have anything to add. I don't play them very often so I feel like I shouldn't really have a say on what gameplay teens need.
