Is This Okay To Wear On The First Day?

I was just thinking about this. I was going to wear some jean shorts, and a gray short sleeve shirt that said," Bon Jovi," and then under it, it said," Bad Medicine." Is that alright to wear on the first day? I was thinking of just curling my hair a little, and just let my bangs go wherever =]. Do you think that would be alright to wear? I mean, if you are my age (12), what are you going to be wearing on the first day? I was just gonna do the casual outfit, and different hairstyle. How is that?
