Shan, I think it's because of the way I'm built. My hips are SO wide, and if I'm not wearing really wide legged pants or a full skirt, keeping my feet close creates a very odd and unflattering line. I need to keep at least about 6" between them to get the graceful, well balanced look that most dancers have.
Ooooo. New fusion style: Sumo Belly Dance. Imagine the costuming.
