Great question. Women have been shown to prefer the scent of symmetrical men and symmetry is associated with attractive features, as well as with hormone levels during development. I\'ve suggested several times that maintaining height to weight proportions that are typically normal, also promotes a good pheromone signature--like tanning, and body building--anything that increases testosterone in men; or estrogen in women (men prefer the scent of women who are ovulating=higher estrogen levels. Beyond that, the link to beauty (or not) is likely to be a matter of personal preference developed with exposure to pheromones of many different types of people.
