Casual has gone so casual... I don't know.... The people of Walmart, are not just in Walmart. No one care's what they look like anymore... Is it TV's fault? Is it the internets fault? I don't think that the majority of people ever "cared" about what they look like. Of course, if you looked to the entertainment world or the aristocrats, you'd have seen fashion "do" more frequently than fashion "don't," but the working class and the laborers were never "Dapper Dans." That's an idealized myth in the same category as the one that states, "Through most of history, women stayed home and men went out to work." The fact is, that the majority of the people who we see in our daily lives are working class people or those who work lower-level, de-skilled jobs. The others, are people who grew up in working class families and who only wear suits because it's their job to do so.
