Self expression-  the expression of one's individuality (usually through creative activities).

Does creative activities include the way we dress? 

What is a (creative) activity limited to? 

Cant you do any thing creatively?

However I feel the by the book definition is very dry, when I feel a persons life is essentially defined by the ways they choose to express themselves. I feel that self expression is the definition of a person. I also feel as though in the modern era where individuality is often encouraged, there are still several parts of the world whose civilians cannot express themselves at all or nearly as much as we can.
