Defining yourself/your family in terms of social class

Without relying on any objective measures, how do you define yourself/your family in terms of social class? Do you think your consumption behaviors and purchases correspond to the defined social class? Explain thoroughly with examples.
Now, use the objective measures/variables including household income, wealth, source of income, occupation, education, place of residence to determine your/your family social class. Do you find any difference to the previous definition and whether your social class and consumption behaviors/purchases correspond?
