I've worn my kilts when it has been 90 degrees or hotter (very low humidity though). As long as you are moving the movement of the pleats keep you cool. Also How hot you feel may depend on what type of head gear you are wearing and what type of shirt, black can get pretty hot. I know from experience thata 9 yard heavyweight kilt with a short sleeved white button up shirt topped off with a pith helmet can get pretty damn hot, especially since my hair isn't all that short, sorry no pictures that I canpost.
