"Bag of rags"?... 'nuff said. Cultural Mavens have always set the style trends. Black jazz/blues musicians in the 30's were the first to start wearing oversized clothing as a fashion statement which was quickly picked up by the dancers. The bohemian culture that they spawned were the first to wear all black as a fashion statement, another way to visually distance and distinguish themselves from mainstream society. Clothing can accentuate lines, even though it may hide the limb responsible for the movement. A long dress hides a womans legs but the way the dress flows, swirls, and hangs gives a better and more visually captivating dynamic to strides, spins, turns, and stops. Loose flowing pants do the same for men.
