I know we have done absolutely nothing with costumes, but i have to say, i think they make it much easier to let your guard down. Take volleyball for instance. Once my uniform is on I am a completely different person. It's acceptable to yell and scream and hit other girls on the butt. No one thinks twice about it. When in uniform I take on a greater role. I'm not just #2....defensive specialist, but i'm 1 out of 10 girls that contributes to each point, which leads to winning each game, and eventually each match. That uniform gives me the confidence to take on another role and act a way that I may not in everyday life.....it's an amazing feeling.
