Passion for fashion or crazy beauty queens?

Little girls from the UK think that fashion is the most important thing in their lives. They don't do funny things like other girls of their age.
Every morning these girls wake up early to put make-upon their faces and brush their hair. Do you think that is normal?
In my opinion these girls don't enjoy and they waste their time in non-sense things.
I think that it's more important to study and have a good time with your friends that playing to be adults.
