"To me, clothing is a form of self-expression- there are hints about who you are in what you wear." --Marc Jacobs
In my opinion, everyone's authentic self is shown regardless of what one wears. The way a person talks, walks, and even acts are all outward extensions from what is believed in their inner core.
Clothing is simply another layer that adds to an individual's desired persona. Like the old saying goes, "you are what you eat." The same can be said for "you are what you wear." Self-expression is important. What a person wears are another creative outlet into showing a piece of oneself. It shoes what makes you, you.
Whether people decide to wear certain apparel based on their mood, a change in climate, or even simply forced to ear a uniform...the end result will not be same for everyone. Glimpses of each individual will be evident. Everyone is different. Everyone is unique. And that is a beautiful thing to see.
