Black Watch? It's one of the most universal colored kilts in the world!! The sky's (or maybe I should say "Skye's") the limit when it comes to hose colors to wear with BW. My favorite hose color is lovat or ancient blue...with navy blue or red garters/flashes. If you want to go for the military look, you can wear lovat green with red flashes. I sometimes wear tan/oatmeal hose...or mustard. I'd wear red, orange, or claret hose if I owned them. I truthfully cannot think of a hose color that would look BAD with Black Watch...though I would probably shy away from bottle green, navy blue, or black...just to avoid the matchy matchy thing (but I did wear bottle green with red garters at Christmas time).
