Most people walk on two lines and this causes them to wabble from side to side no matter how talk and willowy... walking is supposed to carry us forward, but it carries most of us quite as far from side to side. Think of the energy this wabble consumes! No wonder we look anxious, puffy, and off balance...
By walking on one line a woman will appear more graceful, and if there is any soft drapery about her costume she will seem almost to float into a room. A man will preserve his dignity by not bobbing about, and we will all save energy by the directness of the movement."
