People change their appearance for a lot of reasons. But mosty because they don't like the way they look or someone is bullying them and telling them they are ugly.
It's normal for people to not like the way they look, and i totally understand why would they like to change.
But i don't think it's a good idea to change your appearance because someone want's you to do it!! it's you body, not their. And if they don't like something about your look, they should just not look.
So putting it all together people change their appearance because they don't like the way they look.
