The Giant Sunglass Phenemenon

This is a generic sociological inquiry... WHAT'S THE DEAL WITH THE GIANT SUNGLASSES? I think they are a great leveler of attractiveness. People who are a bit lacking in this field can just slap on the biggest Dolce & Gabana or Gucci glasses and cover 1/3 of their ugly faces. I just bought some of these to cover my ugly face so I know it's true. Something about seeing shiny plastic on someone's face just does something to our inner animal that leaves us gasping for air at our intense love for that face. Maybe it's a symmetry thing? Maybe I'm exaggerating?
