Our coach let the boys wear what they wanted if they made it to districts. I think it was more of added incentive. There are a group of boys that continuoulsy do strange things to their hair...all of them are from different clubs...but they run eachother down each weekend to see who out did the other. I think between the hair and the singlets....it gives them a chance to play around and try to out do eachother....it's all in fun
