Fashion is how a person presents themselves to a public audience. It is present in their apparel, the presence the person carries, how they speak, how they move, and the choices they make.

I feel fashion shows up more in public than in private.

Fashion is a way to gain acceptance, interest, a following, and create controversy. It is an artful expression of self that we create. It can be in selection of what others have crafted or we ourselves have created. You extend a compliment by use of crafted items in your fashion statement.
