>I keep seeing photos nowdays of female dancers in ballet class wearing a pair of white ballet tights over their black leotards,instead of the more usual practice of girls wearing their tights under their leotards.It looks a bit ugly I feel with the back seam of the tights highlighted against the black background of their leotards.Is there any practical reason for girls wearing their tights like this?When I attended ballet classes there was a strict dress code requiring girls to wear their ballet tights under their leotards.[/i]
