Objectives: The convergent orientation of recent Social theory is toward acknowledging the significance of realm of consumption and lifestyle practices instead of production and work in constituting Social identities. This shift in social base of identities can be justified in interrelated processes of modernity. The notion of Lifestyle and corresponding arguments and theories seekto offer a consistent interpretation of Social identity and cultural changes in the content of late modernity. We can conclude that in process of modernisation, particular forms of individualty have developed and have been focused upon and expressed through spheres of Social action - such as taste, manners and fashion which are conventionally taken to be the province of Lifestyle practices. These spheres of Social action have become increasingly important in describing Social Life as other forms of structural distinction have come to be seen less important. Method: These hypothesis are studied through Delphi Method, on the mid-youth in the age range of 15 to 29. Conclusion: The basic and general question of this study is to elevatete the possiblity of explaining Lifestyles simmilarities and differences of Lifestyles can be the measure of new Social grouping that is to determine borders of social differentiation or identity from a critical review of litrature.
