A circle of friends can together slowly become an alternative group through mutual support and encouragement. A group of people who know each other give off a group confidence that can create an aura around them - which is often misread by people to mean that they are an exclusive group. This is particularily true when the group develop a particular appearance, or a group aesthetic is formed. The asthetic that the group develops towards is most often a function of their personality - ie, there is a correlation between habits and the aesthetics people are most comfortable with. Subconsiously if not consciously, people learn which aesthetics are connected with which interests and therefore a person can sometimes be drawn to a particular look or style for reasons they do not understand, but is in some way connected to their need to socialize.
