That interest appears to be a specific "fascination" with that particular look. It reminds me of the movie "What's Eating Gilbert Grape?" when Gilbert's (played by a much younger Johnny Depp) obese mother made a rare journey into town to rescue her mentally challenged son, Arnie (played by a much younger Leonardo DiCaprio) and to admonish the police officer who jailed him. The small-town crowd that gathered, snickered, jeered and at best, turned away when they saw her walking back to the car. Their fascination was uncomfortable and also reprehensible for me. I feel that same discomfort when I see the various "fat girls in short shorts" search phrases. To each his own.

With the number of hits my blog has received over the past three months, it very well could become a recognized classification. When a significant number of people use the term and agree to its definition, it is essentially a category or classification. As far as who originated the term "comfortable casual", I have no idea; it wasn't me. I did provide my definition on my May 7th, 2012 post, but I can't imagine that I would have been the first to do so either.
