Just have an easy style. Most high schools aren't too uptight. It's a new start, to make new friends and become a new person, so try and start with a new style! Just go with whatever you think looks good on you. I personally like the surfer style on guys (hehe) so maybe try some shorts and a surf brand tee, flip flops. Go with whatever you like! Good luck!
My best bet: Wear colors that flatters you and your body.
my high school so boring uniforms
I personally like the clothes they sell at Hurley, volcom, jacks surfboards, hss, quicksilver, etc, on guys. I'm a sophomore in high school
