[Sangetsu]

It's true at my school. No makeup, no jewelry, and no dyed hair either. Girls tend to push the limit by shortening their skirts, and boys tend to wear baggier fitting clothes as a way of "expressing themselves".

Girls tend to roll up their skirts a little bit more once they are out of sight of the school. Some schools have taken to using one-piece uniforms for girls, which makes shortening the skirt more trouble than it's worth (though some girls have figured out how to do it).

The only young people I see with makeup, dyed hair, and the like are the "yanki" kids. These are the "ghetto" folk of Japan. They are usually part of the poorer class, and many are dropouts.
