How would you improve Teens?

I hate the teens! Yeah ok, I am not too worried about them being shortened at the moment but it is about time they had their own hairstyles and wardrobe! I am sick and tired of looking for sims that my YA sim could date only for it to be a teen!!!
Maybe a few teen-only aspirations would be nice BUT I just really want them to have their own clothes and hairstyles so I can tell them apart just by looking!
